key to default formatting

I used to use ctl-m to clear direct formatting of a cell but this key closes the document.
Has the key combination changed?

Hello James,

I used to use ctl-m to clear direct formatting of a cell but this key
closes the document.
Has the key combination changed?

<Ctrl>-M still clears direct formatting here (LO 6.4.4.1, Debian
testing).

Have you, perhaps inadvertently, assigned the same key combo to close
document?

In any case, you can check out and modify the key assignments here :

Tools > Customise > Keyboard tab

At least this is where it is done in v 6.3.5.2  (where Ctrl M is set as clear formatting )

I have nothing set beside ctrl+M.
I set it to "Clear".
It doesn't say "Clear Formatting" and there are two entries named Clear".
I think it doesn't like my video card because the UI all seems small.
