### Removing blocks of text in code files

- `c + i + t` will remove the code between HTML tags, such as: `<div>Some content</div>`
- `c + i + }` will remove the code inside of a JavaScript function

### Running terminal commands (without closing vim completely)
- `:! <your command here>`

### Suspend File (close file without saving and without losing your work)
- `<ctrl> + z`
- View "open files" with `jobs`
- open job with `fg`
- open specific job with `fg %<specific job number>`

### Running Macros
- `qr`
- Do the actions you want repeated
- hit escape and then `q`
- `3@r` the number can change for how many times you want to repeat

### Using grep for searching all files
- `grep '<seach_term>' **/*.<file_type>` use `-i` for case insensitive search
#### Use within VIM
- `:grep -ir '<search_term>' .`. This willl open the first matched pattern, to browse through them use `:cn` and `:cp`. To see the quick list use `:copen` and `:cclose` to close the quickfix list. 

### Running Javascript without saving file
- `w !node`

### Personal settings
