Window management

Snap the window you're working in to a half, a third, a corner or the full screen by typing its name or pressing a hotkey you choose. To keep every window side by side on one long row, see Window Strip; to jump between windows, Switch Windows.

Move a window

  1. Work in the window you want to move, then open the bar.
  2. Type the command, for example left half or maxi, and press ↵.
  3. The bar closes and the front window of the app you were in moves.

Type window management, snap or tile to list every command, the everyday ones first. Positions fit the screen the window is on, leaving the menu bar and the Dock clear.

Accessibility. Moving another app's windows needs the Accessibility permission. If it isn't granted yet, Saiki shows you how to grant it, then moves the window as soon as you have. See Install and permissions.

Repeating a half

Run Left Half again on a window that's already there, and by default it becomes two thirds of the screen, then one third, then back to half. Right Half, Top Half and Bottom Half work the same way: ½ → ⅔ → ⅓.

Settings → Window Management → Repeating a half changes this: Steps ½, ⅔, ⅓ (the default), Moves across displays (each repeat moves the window one half further that way, on into the next display), or Does nothing.

Left Half pressed three times on a hotkey you've assigned: half, two thirds, one third. Then maxi in the bar maximizes the other window.

Restore

Restore puts a window back where it was before Saiki first moved it, with its old size. It works on windows Saiki has moved.

Gaps and Stage Manager

Hotkeys

No window command has a hotkey to start with. Give any of them one on Settings → Hotkeys, in the Window Management section, and it works from any app without opening the bar. See Hotkeys and aliases.

Keys from another window manager

Coming from another app? Settings → Window Management has a row for each set of keys; press ↵ on it to give every command those keys at once.

RowKeys
Use Rectangle / Magnet Keys⌃⌥ with ← → ↑ ↓ for halves, U I J K quarters, D F G thirds, E R T two thirds, ↩ Maximize, C Center, = − larger and smaller, ⌫ Restore; ⌃⌥⌘← → other displays
Use Spectacle Keys⌥⌘ with arrows for halves, F Maximize, C Center, Z Restore; ⌃⌘ and arrows for quarters; ⌃⌥⇧← → smaller and larger

Settings

Settings → Window Management has the switch for the whole feature (on to start); turned off, the commands leave the bar and their hotkeys stop. Its Placement section holds the gap, Stage Manager and repeating-a-half settings above.
