AWS has this thing that allows you to connect to an virtual machine from the web console, giving you browser based terminal. Very convenient and nifty. Except using ^W to delete word is so hardwired in my muscle memory that I ended up accidentally closing the tab (and losing state) endless times... I don't think its solvable problem
That being said, same issue happens, albeit to a lesser degree, with desktop apps where occasionally the DE/WM shortcuts conflict with some applications shortcuts.
In Firefox you can enable the ui.key.textcontrol.prefer_native_key_bindings_over_builtin_shortcut_key_definitions setting, but I think you also need to enable Emacs keys in Gtk.
With this I'm able to use Ctrl+w normally in the Gitpod terminal, so this might work for the one in AWS as well.
