Window snapping shortcuts you should actually memorize
The handful of shortcuts that cover almost every layout you'll ever need, plus the cycling trick most people miss.

JgDo ships with ten built-in layouts, but you don't need to remember all ten — a handful of shortcuts cover almost everything.
The core four
| Shortcut | Result |
| --- | --- |
| ⌃⌥← | Snap left half |
| ⌃⌥→ | Snap right half |
| ⌃⌥↑ | Snap top half |
| ⌃⌥↓ | Snap bottom half |
That's enough for most side-by-side work. Corners, maximize, and center have their own single-shot shortcuts listed in Settings → Shortcuts.
The cycling trick
Press the same edge shortcut again and it doesn't just repeat — it cycles. ⌃⌥← the first time snaps to exactly half. Press it again on the same window and it steps to two-thirds, then to one-third, then back to half.
This is the fastest way to fine-tune a layout without dragging an edge by hand: pick a rough side, then tap the same key until the width looks right. A small "2/3" indicator appears on the window so you always know where you are in the cycle.
Anything that resets the window's position — a manual drag, switching apps, or a different shortcut — resets the cycle back to the first step.
Preset sizes, not scaling
⌃⌥⇧, and ⌃⌥⇧. grow and shrink the frontmost window between fixed presets (30%, 50%, 70%, 90% of the screen), centered on the display. These aren't relative to the window's current size — they always land on the same set of steps, so repeated presses are predictable instead of compounding.
Dual-app tiling
If you want to snap the front window and automatically tile whatever's behind it, that's a separate action in Settings → Shortcuts → Layouts. One press gives you a complete two-window layout instead of just moving one window.
Make it yours
None of this is fixed. Every shortcut above can be rebound from Settings → Shortcuts, and JgDo will warn you if a new combination conflicts with something you've already assigned.
