Notebook: Delete shortcut "D,D" does not work on chrome/firefox on mac osx

[motleytech]

The D,D shortcut specified in the help menu seems to do nothing on chrome and firefox on osx. I have not tested on windows/linux, so it might work there. I am running the following (from notebook help -> about)

The x cut cell shortcut works on both chrome and firefox. If this is what users should use, then we only need to fix the documentation... but it still is a hack and it might remove the last copied cell from the clipboard (without letting the user know).

Are you sure you are typing it correctly - the actual keystrokes are d d (no comma char).

Feel like an idiot... I should have tried the dd (duh vim). The comma threw me off.

Hmm. I got stuck on this too. But I don't feel like an idiot. I feel like I've been misled by inadequate documentation. Are there any other characters in the shortcuts that shouldn't actually be typed?

When you see e.g. 'Shift-M', the - shouldn't be typed.

Fair enough.
But hyphenation is a pretty common convention with “mode keys”, meaning ‘simultaneously pressing the two keys joined by -’ ?
(So common, I didn’t even notice it was there.)
Can the same be said for comma (in the meaning 'sequentially pressing the keys separated by , ‘) in any domain?

I don't know of many applications that have shortcut sequences like that. Emacs appears to use spaces to separate consecutive parts of a shortcut. Maybe that would be a bit better, but I suspect someone is going to get confused whatever we put.

I got confused too. And I also believe people will get confused by any notation.
I think it should be made explicit in the help page than "X,X" mean "press X two times quickly".

I think it's a good idea to just write what you are supposed to do in parenthesis instead of using a shorthand notation like @dionisos2 suggested
