I am wondering how can I make a complex multi-key combination like say, Ctrl+Alt+T into a shortcut to execute me a process,
xterm for instance? The important caveat is that I want it wired into either X itself or at an even lower level of abstraction. The reason is that I want it to work across display- and window managers, desktop environments and their own input event stacks, also because I don't want to customize each and any of them to produce the same behavior.
I have noticed there are a lot of questions pertaining to input in UNIX/X but most of them deal with remapping/fixing single exotic keys or I end up with
xbindkeys tool. Am I really left with no other choice? No
XkbOptions wizardry to the rescue? Or
I'll repeat again - I know of countless ways to actually do what I ask for in say GNOME or OpenBox, but I have gotten tired of learning new tricks for the same old thing, and in particular of having to duplicate the behavior with different mechanisms. Ideally, this would be something X can do alone.
