Keybindings

Keybindings

synui's defaults. Override in ~/.config/synui/synuirc or /etc/synui/synuirc.

Lost? Super+C opens the control panel — the front door, listing every shortcut, generated from the live bind table so it can't drift from reality. Tapping Super alone opens the start menu.

Launching and the AI

Key	Action
Super (tapped alone)	Start menu (the bar's SYNAPSE badge)
Super+C	Control panel — every shortcut plus the settings
Super+Return	Open a terminal
Super+Space	Command bar
Super+Backspace	Ask the AI
Super+A	Neural activity overlay (live synapd feed)
Super+Escape	Menu

Windows

Key	Action
Super+Q / Super+Shift+Q	Close window / quit compositor
Super+J / Super+K	Focus next / previous
Super+H / Super+Shift+L	Shrink / grow master area
Super+F / Super+M / Super+N	Float / maximize / minimize
Super+Shift+F	Fullscreen (forces it — for games that only do "borderless")
Super+Tab	Cycle layout
Super+O / Super+Shift+O	Move window to next / previous monitor
Super+1–9	Switch workspace
Super+Shift+1–9	Move window to workspace

System

Key	Action
Super+D	Display settings (p sets the primary output — see below)
Super+W	Wallpaper picker
Super+E	Visual effects panel (scanline / curvature / aberration / glitch sliders)
Super+P	Power saving panel
Super+L	Lock screen
Super+G	Game mode
Ctrl+Alt+Delete / Super+T	Task manager (processes, CPU/RAM/GPU)
Super+Shift+C	Cat mode 🐈

Screenshots

Key	Action
Print	Screenshot the monitor you're on
Shift+Print / Super+Shift+S	Screenshot an area (drag it out)
Ctrl+Print	Screenshot every monitor at once

Screenshots land in ~/Pictures/Screenshots and on the clipboard, so you can paste one straight into a chat without opening the file.

Note: Print arrives as Sys_Req when Alt is held — that's an X11ism, not a bug.

Two things that will confuse you if you hit them

Super+Shift+F exists because "fullscreen" is a lie. Some games (Doom KEX with v_windowmode=1) are borderless windowed and never send _NET_WM_STATE_FULLSCREEN, so the compositor correctly tiles them and you assume synui is broken. Either set the game to true fullscreen (v_windowmode=2) or force it with Super+Shift+F.

Set a primary output if games open on the wrong monitor. Xwayland used to mark no primary output, so SDL fell back to connector order and games opened on whichever panel happened to be first. Super+D → p, or primary=1 in outputs.conf.
