I was trying some keyboard shortcuts and so far this was the only one that didn't work in windows.

#9276 seems to be caused by this. i would suggest reverting or making it conditional.

This commit causes the delete-previous-word shortcut to send Ctrl + W which in bash shell causes it to delete including semi-colon, hyphen, and the like (unlike the current one which treats them as word separators). Would it be possible for it to send Alt + Backspace for delete-previous-word (or assign that signal to a new hotkey)?
