Ctrl+pgup not working

Ctrl+PgUp or PgDn only works for the first press, after that nothing until I click the mouse on another page, then, again, I get one action from the keystroke and nothing after. Same result with previous version 24xxx.

Version: 26.2.0.3 (X86_64)
Build ID: afbbd0df0edb6d40b450b0337ac646b0913a760c
CPU threads: 4; OS: Linux 6.1; UI render: default; VCL: gtk3
Locale: en-CA (en_CA.UTF-8); UI: en-US
Calc: threaded

Ctrl+Home / End work fine.

BTW:

says:
“Ctrl + Page Up/Down: Move to the previous/next sheet”

whereas:

says:

Switch cursor between text and header
Ctrl+PageUp
Switch cursor between text and footer
Ctrl+PageDown

The incorrect information is on a third party site

Sure, still you or they might want to know. Nothing probably to be done about it tho. The internet is always plagued by this kind of thing. And the URL makes it look official.

It says so for Calc (“Practical Shortcuts for LibreOffice Calc”)
