Control+Backspace is a common shortcut for deleting the previous 'word' (the previous block of text to some form of white space).
It's very common in IDE's, even FireFox supports it if you type words in the address bar, press Control Backspace and the behavior happens there.
Asking ChatGPT about the origins of this, it points to Control+W originating from Unix Terminals, and how it's been adopted by most IDE's as Control+Backspace.
Microsoft has very poor support for it in their tools, and I use MS products for the bulk of my work.
Moving to non-Microsoft products like Google Sheets, and viola, Control+Backspace works.
Even muscle memory stuff like Control+Shift and left arrow to select previous words; also not supported by Excel, but it is by Google Sheets and IDE's.
> How is what you want different from pressing delete?
Compact and laptop keyboards; sometimes excluded, often poorly/inconsistently sized/positioned.
There's a much better chance of Ctrl+Backspace being a consistent movement independent of keyboard layout, so I can appreciate where the parent is coming from.
Those compact layouts that exclude a delete key typically replace it with Fn + Backspace.
I'm not saying there aren't scenarios where ctrl + backspace would be useful, however the majority of the time I'd argue that delete is available and should be used.
Is the desire for a ctrl + backspace chord coming from some other system where this is the standard keying?
