At the moment, closing tabs in the list of currently monitored applications can only be done using the mouse, by clicking on the upper-hand x or by right-clicking the tab and selecting one of the Close options (Close, Close All, Close Other).

It would be great if the Close option would be accessible via a keyboard shortcut as well. Preferably some default key used elsewhere, like Ctrl-W (Firefox/others?) or Ctrl-F4, but maybe it's best to make it configurable if it's reasonably easy.

Ideally, Close All and Close Other would also be accessible via the keyboard but since these are less commonly used (and pressing that key by mistake would be fatal), starting by making just the Close option accessible is perhaps best.

(Similar to #54 but for a different use case)
