[FEATURE] Add Keychord Support to Keybindings with waybar keychord module.

[amateur-hacker]

I am requesting the addition of keychord support in the keybindings configuration for Hyprland, along with support for displaying keychords in Waybar. This feature is crucial because, without keychords, we quickly run out of available keybindings. Keychords provide greater flexibility in managing keybindings, similar to how they are utilized in Neovim and other window managers like Qtile and Xmonad.

Implement keychord support using Hyprland's built-in submap feature. Below is an example configuration to illustrate how keychords can be added:

bind = $mod1, S, submap, alt+s submap = alt+s bind = , N, exec, playerctl next bind = , N, submap, reset bind = , P, exec, playerctl previous bind = , P, submap, reset bind = , SPACE, exec, playerctl play-pause bind = , SPACE, submap, reset bind = , S, exec, playerctl stop bind = , S, submap, reset bind = , escape, submap, reset submap = reset

To enhance the user experience, integrate Waybar support to display the current keychord combinations pressed. Here is an example configuration for Waybar:

"hyprland/submap": { "format": "<span style="italic">󰌆 {}", // Icon: expand-arrows-alt "tooltip": false }

Visual Example:

Benefits: Increased flexibility and extensibility of keybindings. Avoid running out of available keybindings. Enhanced usability and user experience with visible keychord combinations in Waybar.

By implementing this feature, we can significantly improve the usability and customization potential of Hyprland. Thank you for considering this feature request.
