1. ciw and diw are pretty cool. you don't have to hop back to the word boundary, you can just delete or change the word. You get yiw too, etc etc.
2. # and * over a word will highlight all occurrences of that word and move backward and forward
3. t/T and f/F are for hop, basically, and t stops before, f stops on, the character.
4. C-r is redo
5. Don't forget o and O, which open a line above (below)
6. A gets you to the end of the line and into insert mode
7. Remember to use your old friends ^ and $ and their additional buddy 0
8. the % character in normal mode lets you hop to a bracket's pair
9. [m and ]m take you to top and bottom of method.
10. g; and g, jump to previous/next change (on change list)
11. The quickfix list is :cl and :cc :cn etc. Also there is the local list ll, which is like a buffer local quickfix list.
12. CTRL-o and CTRL-i to walk the jump list (a list of where you've been in the buffer)
13. gi takes you to your last insert; gv the last visual mode selection; gn the last search match; gI insert text at beginning of line
14. in Visual mode, ip and ap (also Ip and Ap) take yuou to the paragraph boundaries; you can also config function and class (it's textobj treesitter plugin)
15. Ranges also matter. Rangers can be:

• Line numbers
• The current line, .
• The last line of the current buffer, $
• The entire file, %
• The last selection, *

16. Here are some cool registers:

• The unnamed register "
• The read-only registers ., %, :, las:e ~t insert, current filename, most recent command
• Alternate buffer register #
• Black hole register _
• Last search pattern register /
• you already know about =, system(), etc. and + and *

16. :&& and :~ repeat the last sbustitute and redo the substitute with the last search (whew)
17. & in normal mode repeats last sub without its range and flags. g& uses last search instead
18. Marks. Don't forget marks. Special marks: '< '>
19. \[ ]` first/last character previousl yyanked content marks
20. Double-backslash move to position before the latest jump
21. Move the position to where closed file last time
22. ``^`
23. Fuck. Digraphs with CTRL+K are a thing

Ctrl-a Ctrl-@ spit last insert (latter form ejects from insert mode after) Ctrl-o in insert mode gives you oneshot of normal mode (nm 'o'neshot)

Ctrl-d in insert mode changes line indentation, cruically you can be anywhere on th line Ctrl-t increases indentation

Ctrl-u (delete everything 'u'ntil cursor)

Ctrl-w (delete word under cursor)

Ctrl-h (same as mashing that backspace)

Ctrl-r Ctrl-r (double tap) is a verbatim mode useful for managing macros. A single Ctrl-R <reg> doesn't do it Ctrl-r Ctrl-p does paste mode oneshot

gi gI gn
