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.
Thanks for the suggestion with xremap. I knew some X utils would fix this. GTK (so for some browsers) has an Emacs mode out of the box; I used to use it, but C-w was still being overridden.
