This application lets you assign commands to different hotkeys combinations, switch to windows created by these commands.
For example, assign KMail to Ctrl+Alt+M and instead of looking for KMail on the taskbar, running it from the menu or pressing Alt+F2 and typing 'kmail', having two or more Kmail's running, simply keep pressing Ctrl+Alt+M all the time and KHotKeys will take care of it.
Please note that this is v0.2 and it's likely that there are ( many ? ) bugs, although I use it without problems.
Autodetection of window properties
Regular expressions for properties
Executing URL's without typing 'kfmclient openURL'
Keyboard macros ( configuration not complete yet )
The first one - the most buggy one
