Fine-grained width adjustments with the keyboard:

ActionDescription
Hyper+LOption+-Shrink the column width by one step (25% buckets)
Hyper+LOption+=Grow the column width by one step

Width Steps

You can also step the width of a column with shortcuts. Shrink (Hyper+LOption+-) and grow (Hyper+LOption+=) move the focused column through four fixed steps. The steps are 25%, 50%, 75%, and 100% (full width) of the tiled area. Each column remembers the width that you select.

100%
75%
50%
25%

Toggle Full-Width

Press Hyper+F to toggle the focused column between its current width and the full width. The column expands to fill the whole tiled area. The other columns scroll off to the side. The previous width is saved. It is restored when you toggle back.

Remembered Widths Across Display Changes

A width you set by hand, with the keyboard steps or an edge drag, is kept as a proportion of the tiled area, not as raw pixels. That means it survives events that rebuild the layout:

See Multi-Monitor for how windows move when a display is disconnected, and for the move-to-monitor shortcuts.
