TIL Alt-clicking in the Terminal prompt lets me move the cursor to that position. How had I not discovered this over many years?
Not having this has been my #1 Terminal frustration for years... and it's been there this whole time?!?!
This type of thing has actually happened to me several times in the past year or so, where I'd be frustrated an obviously good feature doesn't exist, I'd Google it to see if other people complain about the same thing... only to find it exists after all.
There needs to be a word for this...
It's been one of my #1 terminal frustrations, too!!! But instead of relying on GUIs and the mouse, I started to use terminal tools and wrote a plugin for tmux that helped me. https://github.com/schasse/tmux-jump
Maybe it's useful for you.
