Scrolling
The wheel and trackpad scroll the pane’s scrollback. All of it lives under Settings → Terminal → Scrolling:
⌘ plus the wheel zooms the font instead of scrolling.
A scrollbar appears down the right edge of the pane as soon as the view moves,
and fades out once it stops — the same bar the sidebar and every list in the app
use. Drag its thumb to travel the whole scrollback at once, or click the track
to jump. A pane sitting at the live edge stays bare, however much output is
running through it.
The pointer
Under Settings → Terminal → Mouse:Font size
The base size is Settings → Appearance → Typography → Font size, 15 px by
default. The rest of the interface has its own size — Interface font size,
16 px, adjustable from 12 to 24 — so you can scale the chrome without touching
the terminal grid, or the other way round.
The bell
Settings → Terminal → Bell → Terminal bell decides what^G does:
Command-finished notifications
Settings → Window & Tabs → Notifications posts a desktop notification when a foreground command finishes:- Notify on command finish — Never, When unfocused (default), or Always
- Notify threshold — how long a command has to run to qualify, 10 seconds by default
