- there's a visual mode for selecting text
- I can now yank and paste text in normal mode
- I learned to use :split and :vsplit to open new files, and ctrl-w to switch between them
- I learned a few new navigation commands
- I learned that there's a replace mode (R)
Definitely useful, and I hope I remember everything the next time I open vim!
But I still feel like I'm just scraping the surface. One hour is very little time to learn about the power of vim.
