I am not sure if is my question clear enough so here is some explanation what I am trying to achieve.
I need to create custom shortcut to run hamster (time tracker) to track new activity. The command is:
$ hamster start <activity name>
so I want to press the hotkey ( Super+H ) and then want to be prompted for activity name. Then the text I will enter will be used in the command
$ hamster start <my entered text>
Thanks a lot.
