Unknown? You can't work inside Windows at all without those shortcuts. In Emacs it's alt+Backspace, so it's not too hard to organically find in other environments by trial and error. Whenever I switch editors, I quickly look for the following shortcuts: * How do you delete a word forwards and backwards? (there might be a better shortcut such as Ctrl+W) * How do you move to the word ahead and the word behind? * How do you kill a line? * How do you duplicate a line? * How do you move a line up and down? * How do you activate multiple cursors? * How do you comment/uncomment a line/block? * How do you expand/contract a selection? I think that covers about 80% of the common actions, and learning them will make you instantly productive in your new editor.
