Panes & Splits

Splitting

Split the focused pane into two:

• Ctrl+Shift+D — Split right (vertical divider)
• Ctrl+Shift+E — Split down (horizontal divider)

New panes inherit the working directory of the pane they were split from. Splits can be nested to any depth — split a split, split that split again.

Navigation

Move focus between panes spatially:

• Alt+Left / Alt+Right / Alt+Up / Alt+Down — Focus by direction
• Alt+] / Alt+[ — Cycle through panes in order

The focused pane has an accent-colored border. Unfocused panes are dimmed slightly.

Resizing

• Alt+Shift+Arrow — Resize the focused pane in a direction
• Ctrl+Shift+= — Equalize all pane sizes
• Mouse drag — Drag any divider to resize (5px hit zone)

Content reflows to fit the new pane size as you resize.

Zoom

Press Ctrl+Shift+Z to zoom the focused pane to fill the entire tab. Press again to unzoom and return to the split layout. While zoomed, all other panes are hidden but remain running.

Floating Panes

Floating panes overlay the split tree. They can be dragged, resized, and stacked:

• Ctrl+Shift+F — Create or toggle a floating pane
• Ctrl+Shift+G — Move the focused pane between floating and tiled

Floating panes snap to edges and enforce minimum dimensions. They have proper z-ordering — click a floating pane to raise it.

Undo / Redo

Every split, close, and layout change is recorded:

• Ctrl+Shift+U — Undo the last layout change
• Ctrl+Shift+Y — Redo

The full history of split tree states is preserved for the session lifetime.

Closing

Ctrl+W closes the focused pane. The split tree collapses automatically — the remaining panes expand to fill the space. If it's the last pane in a tab, the tab closes.
