Htop Navigation, Search, Filter, Sort, and Tree View

Basic navigation keys for long lists of processes.

Quickest way to confirm key bindings in the current build.

Useful when the process list truncates long command arguments.

Persistent configuration is adjusted through the setup screen.

Lets you switch sorting without restarting htop.

Useful when you need to flip from heaviest-first to lightest-first quickly.

Searches displayed command lines as you type.

Filtering is case-insensitive and supports multiple terms separated by `|`.

Shows parent-child relationships between processes.

In tree view, `+` and `-` control one subtree, while `*` expands or collapses top-level trees.

Refreshes about every second and surfaces CPU-heavy tasks near the top.

Handy for database process trees such as background workers and child processes.
