@smellsofbikes Today was a bit special, I got burned by the lack of the feature I needed to temporarily see the definition, and lost a bunch of work.

Left has no undo, but it can quickly rename buffers, so I tend to just "stash" copies of the things I'm working on in temporary files. The problem that happened was that when I mouse2 on a word, it copies the selection into a buffer, and it overwrote what I had stashed.. I lost more time with my misclick than I spent implementing scroll-to nav.
