- **Combine motions**: `d3w` deletes 3 words, `y2j` yanks 2 lines down
- **Inside/Around**: `ci"` change inside quotes, `da(` delete around parentheses
- **Jump to character**: `f{char}` jump forward to char, `F{char}` jump backward
- `;` repeat last f/F/t/T, `,` repeat in opposite direction
- **Macros**: 
  - `q{letter}` start recording to register
  - `q` stop recording
  - `@{letter}` play macro
  - `@@` replay last macro

## Command Line Tricks
- `:!command` - Run shell command
- `:r !command` - Insert command output
- `:%!command` - Filter file through command
- `:term` - Open terminal in vim

## Marks & Jumps
- `m{letter}` - Set mark

- `''` - Jump back to previous position
- `Ctrl+o` - Jump to older position
- `Ctrl+i` - Jump to newer position

## Pro Tips
- Use `.` to repeat your last change - super powerful!
- Learn to use `ci"`, `ci'`, `ci(`, `ci{` to change inside quotes/brackets
- Combine counts with motions: `3w`, `5j`, `2dd`
- Use relative line numbers (you have this enabled!) with counts: `5j` to jump 5 lines down
- System clipboard integration: Just yank normally with `y` - it copies to system clipboard! (You have `clipboard=unnamedplus` set)
