cell types for new cell above/below

[baikal]

Describe the bug

Clicking the + creates python cell (as fixed in #7371), hovering reads "CtrlClick" for other cell types. But Ctrl-Click does not (Windows 11), after some trial and error turns out, that "WindowsKey"-Click does it. Though that opens the system-applications-menu as well.

Is that (Windows-Key instead of Ctrl-Key) on purpose or an oversight or just a documentation issue?

What other way is there to create a setup cell?
That might be a good thing to have in the button-bar below the last cell as well.
It used to be in the 3-dot-menu/context-menu (or maybe it was "convert to setup cell"). Only other way I found is in ctrl-K and typing "setup".

Code to reproduce

not needed

in 0.18.0 it was 'right-click for other' and that workes ok on Windows 11, so mayby just go back to that ?

Not on purpose, it should be control key. Might be a bug on our end.

checked on Ubuntu Linux, with "Ungoogled Chromium" (Version 142.0.7444.162), ctrl-click does nothing as well.

Found the "add setup cell" in the main menu (hamburger top right).

Suggestions:

• please restore the 'right-click' behavior on the + buttons to get that cell type choice (the normal context menu does not make to much sense here, is available on the who cell area otherwise). That felt perfect.
• maybe add a "convert to setup cell" entry to the context/3-dot-menu (same as with "convert to markdown/sql") - at least if there is not already a setup cell. I find that a typical usecase - having a cell which basically contains most of the setup-stuff already.
• maybe add a button on the button-bar at the very bottom for setup-cell as well
