A really cool feature in a lot of programs, is the option to have some really convenient shortcut be a configurable one, where the user can assign a few common actions. An example would be blender's bindings for the space button.
Ctrl + Space for examle seems to have the function "Select or deselect the tab with the colored border" I couldn't find out what that does, but after pressing it severel times in various places, nothing seems to have happened. I'd say that's kind of a waste for such a convenient shortcut.
One of the bindable features could be "Search ... for ..." from the context menu! 😉
