Hi - a way to bring keepassx to front with a global keyboard shortcut is needed; in Keepass 1.x and 2.x this is done with "Ctrl-alt-K"
This is different from the "global auto type" (which works great), it is needed so that you don't need the mouse when you need to look something up in keepassx or create a new entry etc.
In linux, this would be doable if there were a command line option in keepassx that would raise the current running instance instead of opening a new one, and then using gnome's "keyboard shortcuts" configuration utility to create a shortcut to /usr/keepassx --raise-running-instance
Apparently there is no such option currently:
~$ keepassx --help
Usage: keepassx [filename] [options]
-help This Help
-cfg <CONFIG> Use specified file for loading/saving the configuration.
-min Start minimized.
-lock Start locked.
If there are developers around, can you confirm if this is the case? if so, I will create a feature request.
