Hi at present please use shift+b and shift+m

Yes I knew that one but I have problems using my left hand and shift-m is quite a stretch for my right hand fingers. Best regards

@MikeDB, Did you know that you can remap the hotkeys? I don't think you can add extra ones but you could perhaps swap them around to make the ones you use more frequently, less awkward key combinations? 

Ah no I didn't.  I do try to do everything with the mouse but keys not using a shift or ctrl key works. Only thing is I can't find that menu you show.  Where is it accessed from ? Many Thanks Mike

  There's a Help section for them under the ? help icon too. :)

Ah thanks  - those are the icons that don't show up on my screen as I've got a magnification factor set for all programs and most developers forget to allow for it.    Got it now. Many thanks Mike
