Version: (using KDE 4.1.2) Installed from: Ubuntu Packages Often users with more than a single keyboard layout enter text in the wrong layout. This commonly occurs to users who are not looking at the screen while typing. Therefore I propose a similar feature for KDE: When the user has focus on a textbox or input field, and then presses a hotkey (for instance F10) then the text changes to another keyboard layout that the user has configured. For instance, typing "יקךךם 'םרךג" and then pressing F10 would change the text to "hello world". There are some websites that have keyboard-layout replacement features (such as http://gibberish.co.il/english_caps.html which changes English characters to the Hebrew character that is found on the same key) and Windows software (http://www.freeware.co.il/hebrew/) that do the same when the user presses a hotkey. I am filing the wish against Kspell, as I imagine that it would likely be best handled by the spell-checker component, as it already has the code for parsing and replacing text. Feel free to change the component if there is a better place for it.
Here is other Windows software for converting text between equivalent keys on different layouts: http://www.langover.com/
Here is a Firefox addon that adds this ability to Firefox: https://addons.mozilla.org/en-US/firefox/addon/5814 This is a real problem for users of multiple keyboard layouts!
