## Missing features

- Only works on Linux
- Most keybinds aren't implemented
- Mouse usage isn't implemented

## Usage

### Keybinds

- Quit: `q` or `<C-c>`
- Process navigation:
	- `k` and `<Up>`: up
	- `j` and `<Down>`: down
	- `<C-u>`: half page up
	- `<C-d>`: half page down
	- `<C-b>`: full page up
	- `<C-f>`: full page down
	- `gg` and `<Home>`: jump to top
	- `G` and `<End>`: jump to bottom
- Process actions:
	- `<Tab>`: toggle process grouping
	- `dd`: kill selected process or process group
- Process sorting:
	- `c`: CPU
	- `m`: Mem
	- `p`: PID
- Process filtering:
	- `/`: start editing filter
	- (while editing):
		- `<Enter>`: accept filter
		- `<C-c>` and `<Escape>`: clear filter
- CPU and Mem graph scaling:
	- `h`: scale in
	- `l`: scale out
- `?`: toggles keybind help menu

### Mouse

- click to select process
- mouse wheel to scroll through processes

### Colorschemes

ytop ships with a few colorschemes which can be set with the `-c` flag followed by the name of one. You can find all the colorschemes in the [colorschemes folder](./colorschemes).

To make a custom colorscheme, copy one of the default ones to `~/.config/ytop/<new-name>.json` and load it with `ytop -c <new-name>`. Colorschemes PRs are welcome!
