Click-through & opacity

Two controls decide how much the overlay gets in your way: whether it takes mouse input, and how visible its background is.

Click-through mode

Press ⌘⌥⇧M and the overlay stops receiving mouse events entirely. Clicks, drags, and scrolls pass straight through to whatever is behind it — your editor, the coding pad, the meeting window — while the overlay stays visible and readable on top.

The edge hub stays clickable, so you can always end the session or toggle back.

Click-through mode active: the overlay visible over a code editor, with the cursor interacting with the editor underneath and shortcut hints shown on each control bar button.

With click-through on, the control bar shows shortcuts instead of buttons you can press.

Shortcuts become the interface

Because the overlay ignores the mouse in this mode, the control bar displays the keyboard shortcut for each control. Everything remains reachable — just from the keyboard.

Opacity

Glass intensity controls how opaque the workspace background is. Response text and the controls stay sharp at every level — only the panel behind them fades.

Shortcut	Effect
`⌘⌥[`	More transparent — the app recedes into the background.
`⌘⌥]`	More opaque — easier to read against a busy screen.

Hide and show

⌘⌥W removes the overlay from your screen instantly. The same key brings it back, with your session and thread intact. This is the one to learn first — it is the fastest way to clear your screen if the conversation takes a turn you did not expect.

Position and zoom

Shortcut	Effect
`⌥←`	Nudge the window left
`⌥→`	Nudge the window right
`⌥↑`	Nudge the window up
`⌥↓`	Nudge the window down
`⌘⌥=`	Zoom in
`⌘⌥-`	Zoom out
`⌘⌥0`	Reset zoom to 100%

A setup that works well

Meeting window on the left, coding pad centre, overlay on the right at medium opacity, click-through on. You read the overlay without ever clicking it, and your mouse belongs to the editor.
