I've been away from playing for a while and just updated everything and looking to get back to having some fun. I have not played with the latest versions of Sonar Platinum but one simple thing I noticed is that old Keyboard Shortcuts are not working. 
 
A simple example being if I press Ctrl+F6 to select Now and Ctrl+Shift+F6 to select Thru where currently selected it does nothing. Yet if I do it from the menu those are the assigned hotkeys and it works fine. In checking under preferences I see no Keys assigned to these but thinking they were defaults there needn't be any. I also tried loading the provided Sonar Default Keyboard Assignments.Kbn file but that made no difference. 
 
So am I missing something here? I realize the intent is to press F6 and use the selection tool\mouse but sometimes I find it easier. I can reassign the keys but wonder why they are on the menu and do not function as shortcuts?
 
Thanks
 

Hi. Perhaps this will get you up to speed on keyboard shortcuts in the latest version.

All the best.

Thanks. I had read through that though. Unfortunately it has Edit Select but not these particular options which is surprising as they are on the menu.
