## percol
# percol
Provides some useful function to make [percol](https://github.com/mooz/percol) work with zsh history and [jump plugin](https://github.com/ohmyzsh/ohmyzsh/blob/master/plugins/jump/jump.plugin.zsh)
Provides some useful function to make [percol](https://github.com/mooz/percol) work with zsh history and
the [jump plugin](https://github.com/ohmyzsh/ohmyzsh/tree/master/plugins/jump), optionally.
### Requirements
To use it, add `percol` to the plugins array in your zshrc:
```shell
pip install percol
```zsh
plugins=(... percol)
```
And [jump](https://github.com/ohmyzsh/ohmyzsh/blob/master/plugins/jump/jump.plugin.zsh) for `oh-my-zsh` is a optional requirement.
## Requirements
### Usage
- `percol`: install with `pip install percol`.
For default
- (_Optional_) [`jump`](https://github.com/ohmyzsh/ohmyzsh/tree/master/plugins/jump) plugin: needs to be
enabled before the `percol` plugin.
- `^-r` bind to `percol_select_history`.You can use it to grep your history with percol.
## Usage
- `^-b` bind to `percol_select_marks`.You can use it to grep your bookmarks with percol.
- <kbd>CTRL-R</kbd> (bound to `percol_select_history`): you can use it to grep your history with percol.
- <kbd>CTRL-B</kbd> (bound to `percol_select_marks`): you can use it to grep your jump bookmarks with percol.
