LyX ⇒ Hot key sequence for inserting display math formula not working on Mac

[JoeT]

I have been using LyX on the Mac for a while now. I have gotten very used to the Shift-Command-M method for creating and toggling display math formulae.

It does not seem to be work in the latest release on Sonoma 14.6.1 on a Mac mini. I am using LyX 2.4.1 as installed via homebrew.

Command-M will create an inline formula but Shift-Command-M will do nothing. It does not create a new formula and it does not toggle an existing inline formula. If I run from the terminal, I get the following output when hitting shift-command-M:

2024-09-30 10:45:14.624 lyx[17471:24990136] Unable to find object to handle service <_NSServiceEntry - 0x600000629900:

I can create a display formula with Insert->Math->Display Formula - it's just the hot key sequence that fails.

Thanks for any help.

I had a similar problem with MacOS Sequoia.
MacOS Sequoia appears to take the shift-command-M key binding for itself. This prevents it being used as a shortcut to enter a display maths formula.
The binding can be released by unticking "Open man Page in Terminal" in the MacOS Settings -> Keyboard -> Keyboard Shortcuts -> Services -> Text.
