Unable to use the System "Lock Screen" shortcut when DevonThink has focus

Hello,

I cannot use the macOS system shortcut for “Lock Screen” when DEVONthink has focus.

This is the key-chord Control-Command-Q (⌃⌘Q). It works in all other contexts except when DT3 windows have focus. I tested it on two unrelated machines, using macOS Sonoma (14.7) and macOS Sequoia (15.0), with the same results.

Selecting “Lock Screen” using the Apple system menu works as expected.

This is for DEVONthink v3.9.7.

Has anyone else experienced this?

Yes. I hear a faint “beep” when trying Control-Option-Q with DT having the focus – as if it has (re-)defined the shortcut, but can’t execute the function associated with it at the moment.

I’ve just tested it on a 14" MBP M1 Pro running Sequoia 15.1 and DT3 3.9.7, and Ctl-cmd-q locks the screen for me when DT3 has the focus. It seems to work flawlessly every time. (@chrillek it’s Ctl-CMD-q, not ctl-OPT-q - was that just a typo?)

I have a lot of custom shortcuts, and I use several programs which manipulate shortcuts (Keyboard Maestro, Karabiner Elements, KeyCue), so I do tend to come up against this sort of problem, but in this case it works flawlessly.

The only thing I can think of is that it’s language specific. I use the standard GB British English keyboard layout, though it also works on Greek Polyphonic, Maori and Old English as well but it may be worth trying out a different layout.

I’ll check this on my desktop Mac Studio later on.

Working as expected here, macOS 13.7 and DEVONthink 3.9.7

Yes. I tested again with both combinations, always get just a beep.

German keyboard here. I checked my BTT settings and couldn’t find one for Ctl-Cmd-q, nor in Alfred. And the Keyboard Detective app didn’t find anything either.

@brookter, thank you for checking.

I am using the US English keyboard layout.

I tested with and without Keyboard Maestro [1] running and had the same effect with the Control-Command-Q lock-screen shortcut. It does not work with DEVONthink in focus but works elsewhere.

[1]: I quit the entire Keyboard Maestro Engine, not just the GUI editor.

Very odd… Sorry I can’t help anymore!

I just checked the custom system shortcuts. There is nothing defined with this key chord for DEVONthink.

On my device (M1 Mac) ⌘⌃Q had not worked in DT (and only in DT) since I started using the software. I did a factory reset last year and this behavior persisted after that. However, after I upgraded to macOS Sequoia (no other change made), ⌘⌃Q now works in DT.

Works fine on Ventura over here, doesn’t work on Sequoia right after launching the app but works after opening the Apple menu at least once. Might be a bug of macOS as this menu isn’t handled by DEVONthink.

@cgrunenberg, I can also confirm this on macOS Sequoia (15.0).

The shortcut does not work after the app’s first launch, but after opening the Apple menu at least once, it starts working for DT as well.

This is weird, though, since it affects DEVONthink only, and no other application (that I could see).

using also very often lock screen short cut on two MACs. It’s doing the job without any problems.

I’ve just checked this but DEVONthink doesn’t use this shortcut on its own.
