Configure Web Browser to be More Emacs-like

Emacs, LibreOffice Writer and Vivaldi are the productivity tools I use most often. So I like to incorporate a feature from one into the others. One example is the ability to initiate a search from selected text. I added this feature to LibreOffice as described here. Another nice feature is the ability to switch between the current buffer and the next (or previous) buffer with C-<TAB> and C-S-<TAB> that I added to Emacs¹.

But I've also configured Vivaldi with a useful Emacs feature. Now it responds to C-S-k by invoking "Close tabs to the Right." Emacs devotees know that C-k is bound to kill-line, which "Kill[s] the rest of the current line...."² If you imagine that the row of tabs is a line of text, it's natural to expect C-k (or C-S-k) would remove all the tabs to the right of the current tab.

Why did I choose the key combination C-S-k instead of C-k? I think at the time C-k performed another function. Or perhaps I felt that it was more appropriate to use two modifier keys for such a significant operation. I rarely need to delete tabs to the left; if I did, I'd bind C-M-S-k to "Close tabs to the Left."

You might utter the following complaint, "But C-S-k doesn't work for Gmail; it brings up a virtual keyboard instead!" Correct. So while we're on the topic of Vivaldi key configurations, I'd like to point out that it's possible to tell Vivaldi to ignore a website's key assignment, allowing the key to pass to Vivaldi. Just search for the setting "Browser Priority Shortcuts," click on one of the existing key combinations and press C-S-k to add it to the others.

I rely on the web browser's tab history a great deal, too. I'm working on implementing something vaguely similar for Emacs."

¹ To get the C-<TAB> and C-S-<TAB> to switch buffers, just add this to your init file:

  (keymap-global-set "C-<tab>" 'next-buffer)
  (keymap-global-set "C-S-<tab>" 'previous-buffer)
