reformat code

As soon you open a file in VIM, just press the “g” key twice. This should move the cursor to the beginning of the file. Then hit the “=” key. Finally, hold “shift” and hit the “g” key again.

Search

1. Move to the Next Match:

After the first match is found, to move to the next match, press:

n

This will move the cursor to the next occurrence of the search pattern.

2. Move to the Previous Match:

If you want to move to the previous match, press:

N

3. Search Backwards:

If you want to search backward (from your current cursor position toward the beginning of the file), use:

?your_pattern

Then, use n to move to the previous match (in the reverse direction) and N to move in the opposite direction.
