[Feature]: Keyboard shortcut to switch between browser and simulator tabs in the preview pane #17915

Before submitting

• I searched existing issues and did not find a duplicate.

Area

apps/web (right panel / preview pane), keybindings

Problem

The preview pane holds both web browser tabs and simulator/device tabs. There is no keyboard shortcut to move between them.

In the default keybindings, mod+shift+[ and mod+shift+] are bound to thread.previous and thread.next with no when clause, so they switch threads instead of preview tabs. I checked ~/.t3/userdata/keybindings.json. No command in the defaults cycles preview or right-panel tabs. Existing shortcuts in the panel cover only zoom (preview.zoomIn and friends), refresh, and the URL field.

Requested behavior

• A command such as preview.tab.previous and preview.tab.next that cycles tabs in the preview pane, bound by default to mod+shift+[ and mod+shift+] when previewFocus is set.
• Those keys keep thread.previous and thread.next when the preview is not focused.
• Users can rebind the commands in keybindings.json.

Open question

A separate pane for simulators, distinct from the browser pane, may serve better than mixing both in one panel. The shortcut is useful either way.
