keyswap sanskrit iast software

Keyswap – IAST Diacritics Windows Software (for Sanskrit Language Scholars) 

About Keyswap:

Keyswap is a Windows transliteration application that runs in the background.

It let's you add diacritics to roman letters by pressing= after any key.

It was initially made for private use during my years of learning Sanskrit at University. Handwriting was too slow. Hence came idea of typing IAST (ISO 15919) quickly anywhere.

Example how to use:

  • Keep pressing = after letter n and watch it cycle: n > > > ñ > n
  • EG: Rāmāyaṇam, saṃsāra, śiṣyāḥ

Features:

  • Map any character combination by editing config.txt
  • Set any trigger key if don't prefer the default ‘ = ‘.

  1. I’m using the Keyswap and it is very useful. If you are in sanskrit transliteration this should be one of the tool must add.

  2. I have just installed keyswap downloaded from the above link. However, I was trying to type Krsna with the dots under r, s, and n. Pressing “=” worked for r and s. Howver, after n when I press “=”. It is converting Word from Print layout to Draft Layout and it is deleting n. Then “=” works like backspace deleting the typed letters.

    Kindly help.

    1. Here, all letters are working with ‘=’, in any program, including MS Word. Both on Win 7, XP and Win 10. Perhaps change ‘=’ to diff key.

      Also, ensure to run Keyswap as Admin. Right-click: Run as Administrator.

  3. Hi Andre, thank you for your tool! I have just downloaded it, it seems to work beautifully.
    I have been typing IAST for years just in Word after asigning some combination of keys to each letter.
    Eg: (ctrl+alt+acute) + a= ā
    Your tool works in all Windows, so it is a huge plus. It is very helpful.

    My computer has a Spanish keyboard with “ñ” and a slightly different configuration, so instead of “=” I have to use “+” to make Keyswap work.

    By the way, sometimes we need to use IAST with capital letters, when the sanskrit is part of a paragraph in English / Spanish.
    Eg: “Śivāya” means “to Śiva”.
    It would be nice if your tool included the capital letters.

    Thank you!

      1. It didn’t work with Capitals for me. I watched the video (I hadn’t done it before, sorry) and found your explanation about the Config file.
        The file I downloaded didn’t have the Capitals, but I added them now.
        Thanks a lot again!

  4. I use WordPerfect but can’t seem to get Keyswap to work in the program. Any ideas on how I can use it in WordPerfect? Thank you!

    1. Before launching: Right-click on “keyswap” > Properties > Advanced > Run as Administrator.
      Still doesn’t work? Right-click on “WordPerfect” > Run as Administrator.
      Still doesn’t work? No further solutions.

  5. As per dictionaries such as Merriam Webster, an A with a line over it, means it is pronounced as the letter A sounds. Like in Ate, Ape, etc. For an aa sound as in father, far, etc they recommend either two dots or an angle sign: Ä or  BUT NOT Ā

  6. I really appreciate your wonderful efforts to make the software.
    Is it possible to get ‘danda’ the vertical bar and also double bar along with sanskrit IAST characters. The height of default vertical bar that comes is rather too high. Such bar is possible only in devnagari and I want it in sanskrit IAST.
    Thanking you in advance.

    1. Right-click on ‘config.txt’ > Open with > Notepad

      Can add on last line:
      . > | > ||

      This means if you type . and press the trigger key, it’ll change to danda.

      If height is excess, then:
      . > ˡ > ˡ ˡ

      Or can search for more characters. In Win, type in: charmap

  7. Wow. Thanks. Saves so much trouble trying to program keystrokes that don’t always work well across programs. Really, I can’t thank you enough.

  8. I love this tool. I also note that it does not always download – a couple of my colleagues have tried to do so. Note that I am also working on the config file to add some characters for an MIA language. Do you know what I can get the original app? Is there some issue I am missing trying to download. Plese let me know as I love this app. Kate
    BTW – We were in a Sanskrit class together some years ago at ANU

    1. Hi Kate. Part of brain remembers you. 🙂 Keyswap was created for the very reason we were at ANU. I use it daily. Indispensable. Changed download URL to (https), may help. Andre.

  9. I have been looking for a tool, like the one you presented, and watched the video. This is a great humanitarian service. My thanking is too small for what you did. As a senior (82) I only want to Bless You, Andre Vas. Keep Healthy.

  10. Just got a link. A few queries.
    Works in xp, windows 7 and windows 10?
    any difficulty in unstall, if not found working properly?, because, another programme like this after installation (of course without any other bug and a free programme), was not able to download and creates problems in Word and one has to always unlink it from word, windows options, addins, everytime I start Word. Hence the question.
    If it is fine, I will download and try out.

    Incidentally, I just completed the BG Sankara Bashyam verbatim transcription of Swami Paramarthananda’s teachings and the last volume (6th) would be uploaded in arshaavinash.in in a day or two.

    1. 1) Works in all Win versions.

      2) No need to install/uninstall. It’s standalone .exe file.

      3) It doesn’t create problems with any software, as been using it for years, including MS Word.

      Thank you for the service and kindness of undertaking transcription of Swami Paramarthananda’s work.

  11. Wonderful soft, I was looking for something similar for such a long time. So grateful that I would be happy even to donate for it. Thank you so much!

  12. Hi,
    I have been using Keyswap for several months without any issue, but today all of a sudden – after apply = on the second time after “s”, I am not getting the talavya s i.e. sha diacritic. I have tried closing and running it and even deleting the file and downloading again from here, but its still not working. Please advise

  13. This is great. However when I type “t” and then try to put a period after it ,it makes it ” ṭ ” , Isn’t it suppose to change after I press “t” and then “=” ?

  14. Really useful. I have begun to use this for carnatic music notation. I love it for its simplicity. Need not remember combinations of keys. Press = over and over to get what you want. The best part is the configuration file.

  15. Hi,
    Very good soft, congratulations and thanks for sharing it. I have a problem. I accidentally ran it twice, as administrator, and now I have an error message from the OS saying “an item with the same key has already been added”. I don’t know which registry key to delete to correct the problem. I would appreciate your suggestions.

  16. Inexperienced user tried to download from the link above. Barely knowing what I was doing, I did find a choice to “run as administrator”. I see the xx.exe file but don’t understand how to launch the program. I know most people here seem to understand those very early steps but I don’t. Simply put, I see something but cannot get the program to open.

    I wanted to run it because I had trouble to copy/paste from several transliteration tools into PowerPoint (web based, provided to students by college). was working on an iPad which requires the Lexilogos tool, not Keyswap, and I wanted to try Keyswap on an old laptop running Windows to see if that would work. Someone, somewhere must know how to transliterate from Devanagari to some standard useable font/keyboard. Any help appreciated. thanks.

  17. I am in the middle of making my own font, at which point I was trying to figure out an easier way to type accented characters, something I, as a lover of languages, always want to do whenever I talk about or use a word that should have one. While I was contemplating ways of incorporating it into my font itself, I decided I should see if this was a problem that had an easy solution. Last time I looked, there really wasn’t any software available that did it in a way I found satisfactory, but now I immediately discovered yours, which seems to work perfectly.

    By the way, it is mentioned on this page how it only works on a US keyboard layout, but surely the layout is only relevant for the trigger key? I use a Norwegian keyboard and simply changed the trigger key to something else. The next available key that I’d never type just after a letter was |, and so I use that and it works fine.

    Now I just need to redo the config file to put the characters in the order I’d need them, and I’m good to go. I think that will be quite a work in progress as there are many characters I like using that are not available on the keyboard directly. I’d probably want to add some IPA characters too, fractions, dashes, sub- and superscript numbers. The possibilities go far beyond just typing Sanskrit. It also occurred to me having different config files for different typing requirements may be a good idea.

    And I finally don’t have to memorise alt-codes anymore …

    Thanks for making such an easy-to-use application easily available. I will be sure to recommend it to people whenever I see someone who could use it.

  18. Ādeśa – Dear Ācārya Andre,

    Thank you for making your elegant Keyswap program freely available to all.

    Am using Keyswap to transliterate 31 verses of paṭala 20 of the Matsyendrasaṃhitā in Microsoft Word (and it’s making this task so much easier).

    Again, thank you.

  19. Great tool concept.

    Is it possible to download and use on a mobile phone?

    Tried downloading app, but it didn’t appear on phone.

    Thanks in advance.
