keyway-visualizer

Minimal Wayland keystroke overlay using evdev for input and GTK4 + layer-shell for the on-screen display.

Demo

demo.webm

Requirements

  • Linux (Wayland)
  • GTK4 + gtk4-layer-shell dev packages
  • xkbcommon

Arch Linux

sudo pacman -S gtk4 gtk-layer-shell xkbcommon

Build & Run

cargo run

Config

Default config path:

  • ~/.config/keyway-visualizer/config.toml

The file is created on first run. Example:

position = "bottom-right"margin = 40max_items = 5ttl_ms = 900show_mouse = truepause_hotkey = "Ctrl+Shift+P"repeat_coalesce_ms = 200modifier_grace_ms = 120drag_enabled = falsecustom_x = 40custom_y = 40app_filter_enabled = falsedisabled_apps = ["firefox", "org.keepassxc.keepassxc"]

You can override via CLI:

cargo run -- --position top-left --ttl-ms 1200 --show-mouse false

Positions supported: bottom-right, bottom-center, bottom-left, top-right, top-center, top-left, center, custom. Use custom with custom_x/custom_y for pixel placement, or enable drag mode and move the overlay.

Hotkey parsing accepts tokens like Ctrl+Shift+P, Super+F13, and named keys like Plus or Comma for symbols.

Settings UI

Open the system tray icon and choose Settings. Changes can be applied live or saved to the config file.

Permissions

This app reads input events from /dev/input/event*.

If you see "No keyboard devices found" or permission errors:

sudo usermod -aG input $USER# log out and back in

Alternatively, set up a udev rule to grant read access.

Behavior

  • Shows key combos (e.g., Ctrl+Shift+A) in a small overlay.
  • Shows mouse clicks: LMB, RMB, MMB.
  • Items fade out after ~900ms.
  • Pause/resume capture via hotkey (default: Ctrl+Shift+P).
  • System tray menu for pause/resume and quit.
  • Drag mode to reposition the overlay (tray or settings).
  • App filter to disable the overlay for specific apps.

App Filter

App filtering uses hyprctl -j activewindow on Hyprland to match against the active window class or title (case-insensitive). Add one string per line in Settings, or use:

cargo run -- --app-filter-enabled true --disabled-app firefox --disabled-app keepass

If hyprctl is not available, the filter is ignored.

Packaging (manual)

This repo includes example files you can adapt:

  • packaging/keyway-visualizer.desktop
  • packaging/keyway-visualizer.service

sudo pacman -S gtk4 gtk-layer-shell xkbcommon
Build & Run
cargo run
Config
Default config path:
  • ~/.config/keyway-visualizer/config.toml
The file is created on first run. Example:
position = "bottom-right"margin = 40max_items = 5ttl_ms = 900show_mouse = truepause_hotkey = "Ctrl+Shift+P"repeat_coalesce_ms = 200modifier_grace_ms = 120drag_enabled = falsecustom_x = 40custom_y = 40app_filter_enabled = falsedisabled_apps = ["firefox", "org.keepassxc.keepassxc"]
You can override via CLI:
cargo run -- --position top-left --ttl-ms 1200 --show-mouse false
Positions supported: bottom-right, bottom-center, bottom-left, top-right, top-center, top-left, center, custom.
Use custom with custom_x/custom_y for pixel placement, or enable drag mode and move the overlay.
Hotkey parsing accepts tokens like Ctrl+Shift+P, Super+F13, and named keys like Plus or Comma for symbols.
Settings UI
Open the system tray icon and choose Settings. Changes can be applied live or saved to the config file.
Permissions
This app reads input events from /dev/input/event*.
If you see "No keyboard devices found" or permission errors:
sudo usermod -aG input $USER# log out and back in
Alternatively, set up a udev rule to grant read access.
Behavior
  • Shows key combos (e.g., Ctrl+Shift+A) in a small overlay.
  • Shows mouse clicks: LMB, RMB, MMB.
  • Items fade out after ~900ms.
  • Pause/resume capture via hotkey (default: Ctrl+Shift+P).
  • System tray menu for pause/resume and quit.
  • Drag mode to reposition the overlay (tray or settings).
  • App filter to disable the overlay for specific apps.
App Filter
App filtering uses hyprctl -j activewindow on Hyprland to match against the active window
class or title (case-insensitive). Add one string per line in Settings, or use:
cargo run -- --app-filter-enabled true --disabled-app firefox --disabled-app keepass
If hyprctl is not available, the filter is ignored.
Packaging (manual)
