Buffers and Searching Contents

Switching between what is already open#

Once files are open you do not need to find them again — you need to switch.

:b rou               " jumps to routes.py

:b matches against the buffers you already have open, so it is instant. It does not touch the disk.

Searching contents, not names#

When you do not know the filename at all, only something written inside it:

:vimgrep /def/ **/*.py
:copen

• :vimgrep searches inside files and fills the quickfix list
• **/*.py means every Python file at any depth
• :copen shows the results as a list you can walk with Ctrl-n / Ctrl-p
• :cclose puts it away

That is the same quickfix workflow used elsewhere in the course, aimed at your project.
