Keyboard shortcuts: Krova guide

Windows only for now. The global shortcuts need Windows. On macOS the Settings window says “Keyboard shortcuts are not available on this system yet”, and you snap by dragging.

Move the focused window (Windows)

Each shortcut is the modifier keys you chose, held together with one more key. By default the modifier keys are Ctrl+Alt+Shift. They act on the window that has the focus.

Keys (with the default modifier)	What it does
`Ctrl`+`Alt`+`Shift`+`Left`	Move the focused window to the previous zone. From the first zone it wraps to the last.
`Ctrl`+`Alt`+`Shift`+`Right`	Move it to the next zone. From the last zone it wraps to the first.
`Ctrl`+`Alt`+`Shift`+`1` to `9`	Move it to that zone number on the monitor it is on.
`Ctrl`+`Alt`+`Shift`+`Up`	Send it to the next monitor, to the right and wrapping round, in the zone with the same number. If that monitor’s layout has fewer zones, it goes to the last one.

How zones are numbered

Zones are counted in reading order: top to bottom, and left to right within a row (rows are compared to the nearest 1%). In a 2x2 grid, 1 is top left, 2 top right, 3 bottom left and 4 bottom right. In Halves and Thirds, 1 is the leftmost zone. The number is the zone’s place in that order, not an id you can see. With more than nine zones, 1 to 9 reach the first nine and Left and Right reach the others. A number past the last zone does nothing.

Which windows they move

The window with the focus. A maximized window is restored first, then moved into the zone.
They do nothing for the desktop, the taskbar, minimized windows, windows of programs running as administrator, or Krova’s own windows.
They follow the same settings as dragging: animated or instant moves, and the space between zones.
When Enabled is off in the tray menu, the shortcuts are released and do nothing.

Choose other modifier keys

Open Settings from the tray menu, then Keyboard shortcuts. Use keyboard shortcuts switches the feature on or off (on by default). Modifier keys offers:

Choice	Note
`Ctrl` + `Alt` + `Shift`	The default. Accepted for all twelve shortcuts on the Windows 11 PC we tested.
`Ctrl` + `Alt`	Accepted for all twelve there. Some programming tools use Ctrl+Alt+Left and Right for back and forward.
`Win` + `Alt`	Windows refused all twelve on that PC; it keeps these for itself.
`Win` + `Ctrl`	Windows refused eleven of the twelve on that PC; only Win+Ctrl+Up was accepted.

That is one PC and one Windows version, so treat it as a hint. Some combinations can be taken by Windows or by other apps. When Krova cannot register a shortcut, Settings lists it, for example “Win+Alt+3 is already used by another app”. Pick other modifier keys, or close the app that holds the combination. The list updates as soon as you change the choice. If a shortcut does nothing, see Troubleshooting.

In the layout editor

These work while the editor window has focus. On a Mac, Cmd takes the place of Ctrl. The single-letter keys are ignored while a text box has focus, so you can still type a layout name.

Key	What it does
`Esc`	Back to the Select tool; if you are already there, clear the selected zone
`V`	Split vertically tool: the divider is a vertical line, so zones end up side by side
`H`	Split horizontally tool: zones end up stacked
`Delete`	Delete the selected zone; a neighbour that shares a full edge takes its space
`Ctrl`+`Z`	Undo the last edit to the current layout
`Ctrl`+`S`	Save the layout

On a focused divider

Key	What it does
Arrow keys	Move the divider by 1%
`Shift` + arrow keys	Move the divider by 5%

On a zone

Key	What it does
`Enter` or `Space`	Select the zone (Select tool)
Arrow keys	Move the split guide (Split tool); hold `Shift` for 5% steps
`Enter`	Split the zone at the guide (Split tool)

Tabs

On the monitor tabs, Left, Right, Home and End move between monitors. On the Editor / Settings switch, Left and Right move between the two views.

The activation key is a separate setting

The key you hold while dragging (Shift by default) is not one of these shortcuts. It only shows the zones during a drag. Change it in Settings, Snapping, Activation modifier: Shift, Ctrl, Alt, or the Windows key (Command on a Mac). See Your first snap.
