Shortcuts to switch to open applications
Hi Linux Guys,
I am currently running a mac with a utility called 'butler'. Butler is a shortcut tool that allows me to define a shortcut for - let's say - firefox. If I press that shortcut butler opens up firefox if it is not open yet. if I switch to another application, and press that shortcut again, the current instance of firefox will come up again (no new instance is forked). I found various window managers with support for shortcuts, but none that brings the already opened applications upfront. I am aware that alt+tab exists, but is there something that can bring up my already open application by pressing a shortcut for that application?
Thanks for any hints;
