While I grew up on =Control S=, I am liking the /mental model/ associated with the [[https://github.com/abo-abo/avy][avy project]] that allows a /jump/ among matches across all visible windows. I use the ~F18~ key on my keyboard that should be easy to use, but ~g o~ seems obvious.

Want to know something amazing. In a Terminal, like =vterm= or =eshell=, I run ~s-g~ and pinpoint the UUID in the output of a long command. Then type ~y~ and then ~C-y~ to paste that ID without even moving the mouse.

The [[info:emacs#Goto Address mode][Goto Address]] mode (see this [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Goto-Address-mode.html][online link]]) turns URLs into clickable links. Nice feature and built into Emacs, but it requires using the mouse or moving to the URL and hitting ~Return~ (if you like this idea, check out [[https://xenodium.com/actionable-urls-in-emacs-buffers/][Álvaro Ramírez's configuration]] for this).
|

|

I appreciated [[https://github.com/abo-abo/ace-link][ace-link]]’s idea for hyperlinks on Org, EWW and Info pages, as it allowed you to jump to a URL from any location on the screen. The [[https://github.com/noctuid/link-hint.el][link-hint]] project does this, but works with more types of files and links:

Wilfred’s [[https://github.com/Wilfred/suggest.el][suggest]] function helps you find the right function. Basically, you type in the parameters of a function, and then the desired output, and it will write the function call.
