I am trying to get Command+Alt+Shift+L to work in RStudio on OSX. I have a large number of customisations that might possibly prevent this shortcut from working. I've gone through the usual places (e.g., system preferences - keyboard; Alfred; Better Touch tool). Thus, I thought there might be some more general procedure for working out what program, if any, is intercepting the shortcut

Is there a way of seeing what program might be intercepting a particular keyboard shortcut?

does anything happens when you do it ? – Buscar웃 Apr 8 '13 at 8:07
you could look it up in system pref keyboard, shortcuts – Buscar웃 Apr 8 '13 at 8:17
@Buscar웃 Nothing overt happens, when I press the key; I've already looked up system pref keyboard, and I couldn't see anything. – Jeromy Anglim Apr 8 '13 at 9:44

There is app called KeyCue that will help you find the keyboard shortcuts in use by your system.

enter image description here

It is shareware.

More info and to download :

Thanks; From what I can tell, KeyCue does not list all shortcuts. For example, it did not list BetterTouchTool global keyboard shortcuts. – Jeromy Anglim Apr 8 '13 at 9:50
@JeromyAnglim Stupid question, Do the other shortcuts work in RStudio ? – Buscar웃 Apr 8 '13 at 11:26
yes. the other shortcuts work in Rstudio – Jeromy Anglim Apr 8 '13 at 12:36
sometimes and do not ask why, try the right hand alt key – Buscar웃 Apr 8 '13 at 12:48
I think it is the Command+Alt+Shift+(I) or Command+Alt+Shift+l not Command+Alt+Shift+L – Buscar웃 Apr 8 '13 at 14:20
