Who designed these shortcuts? When editing code or inputting text in the workflow, if you accidentally press Backspace one extra time while deleting, the entire workflow node gets deleted immediately. There's no way to recover the edited content, forcing users to write text and code in external editors first. This problem wouldn't exist without these shortcuts - they're more harmful than helpful.

Totally agree! It's super annoying when editing a prompt with a "/" symbol, like in </context>. The variable list pops up every time the cursor hits it, and if you hit Backspace one more time—poof! The entire node is gone, no way to recover it. Happened to me while deleting </context> in a prompt like:

Lost the whole thing, and no redo option. So frustrating!
