Thanks for those thoughts.
I have a few personalised shortcuts, though not enough to cause a real problem if I have to reassign them.
I was only pressing the O key, and I don’t HAVE a + sign in the dialogue:
I get this:
And when I press Enter I get:
I never was able to confirm the assignment of O to Edit/ContextMenu Flyout/Dynamic Components/Redraw - even after accepting the option to replace the already assigned O for Orbit.
I did have my DC selected, and was able to ‘see’ the Redraw context menu when I was trying to set the shortcut.
Maybe the missing + sign is the clue, and my pressing the Enter key after entering a letter or Ctrl is just telling me that I can’t assign the Enter key to a shortcut, which would make a sort of sense?
But I have in the past on this machine been able to assign a custom shortcut - Shift+D for the Dimension Angle plugin. That’s still working, and shows up in the Shortcuts list when I search for Dimension.
And I have assigned Ctrl+V to Edit/Paste in Place - which shows in the Preferences/Shortcuts, and works, but doesn’t show in the SU Edit menu, even though the standard shortcut Edit/Paste (option+V) does show.
In fact, now I look in the SU menus, I can see that the shortcuts shown are all scrambled. Not sure if I can take a screen shot, but (for example) Tools/Tape Measure shows Option+D as the shortcut, but I actually use the standard T.
ALL the shortcuts shown on the Tools menu are wrong.
I’m running on OS X El Capitan v10.11.4 - has this recent update affected anything on SU recently?
This is a bit of a mess. How to recover? Reset All shorctuts, and reenter the custom ones?
Find and delete the shortcuts.plist file, as I’ve seen in other posts about shortcut problems on Mac?
PS. As far as I know, O without a modifier key isn’t a standard Mac shortcut for anything - but I’m new to Macs. It used to work fine for Orbit, and WAS previously assigned to that, though I didn’t use it much.
PPS. Further experiment. If I assign a shortcut key, then click somewhere else, it seems to get saved, even though I haven’t a + button. So, for example, I assigned Y (for Yes) to the DC Redraw command, and it has stuck, and works. But it too doesn’t show as an assigned shortcut in the Context menu list.
And that technique has enabled me to get the O for Orbit back too.
Small but very confusing bug? Where’s the + symbol gone in Preferences/Shortcuts? And why are the menus showing mostly wrong shortcuts?
Only the File menu seems to show all the right shortcuts.
The Edit menu is mostly right, but partly wrong further down, and is missing my Ctrl+V custom shortcut near the top.
The Draw menu is mostly wrong
The Tools menu shortcuts shown are all wrong and also missing my custom shortcut Shift+D for Angular Dimension
The Camera menu shortcuts seem mostly wrong, but I don’t use enough of them to know for sure.
??? Where to go next to fix? Will have to sleep on it - way past bedtime here in UK (1:50am).
