While editing in an input field, I’m so used to going for Ctrl+W instead of Ctrl+Backspace because it’s more ergonomic. But almost all modern browsers use Ctrl + W to close tabs. Since when was this a convention? I’d love to go back in time and git revert this change. Incredibly frustrating.
TL;DR: old man yelling at clouds.
I am not entirely sure, but I think it depends on the page if it warns if text is in an input and you want to leave the page.
