I have (had) one of the Views in View Manager PI assigned to ctrl/alt/p (Published date primary sort column) for some time (at least 2 years). In Windows 64bit version 2.10 its stopped working. It works fine in Windows 32bit version 2.9 on the same library using the same config data - its a view I use daily when I adding articles/papers etc.
Other similar kb shortcuts work - ctrl/alt/d for default view (Author primary sort column), ctrl/alt/u (Publisher primary sort column), ctrl/alt/m to toggle Mark Book etc.
If I change ctrl/alt/P to ctrl/alt/Z it works, I do NOT get a conflict message with ctrl/alt/P or ctrl/alt/Z.
I looked at %CALIBRE_CONFIG_DIRECTORY%\shortcuts\main.json - couldn't see anything 'out of order'. Given it works with 32 bit v2.9 says to me that its not 'interference' by a 3rd party program.
weird, what
Added 1 :Likewise I've had Open With configured to fire up Sigil with Shift/S for a long time, it's also stopped working in version 2.10, again its something I've been using most every day.
Added 2 :And now ctrl/alt/z has stopped working for View by Publisher - I think I'll go back to 2.9. I ran Check Library on my libraries - no errors reported.
Added 3 :Reinstalled 64bit 2.9 - all keyboard shortcuts appear to be working as expected - looks like something amiss in 2.10
