Agents app: keybindings to switch between sessions (Ctrl+1..9) by Copilot · Pull Request #310994 · microsoft/vscode

Copilot · 2026-04-17T13:03:53Z

Adds Ctrl+1..Ctrl+9 to switch between sessions in the Agents window, mirroring the familiar tab-switching pattern.

Ctrl+1..Ctrl+8 open the Nth visible session
Ctrl+9 opens the last visible session (Chrome/Slack convention)
Uses Ctrl on all platforms (including macOS) to avoid conflicting with Cmd+N view-focus shortcuts in VS Code
Gated by IsSessionsWindowContext so regular VS Code shortcuts are unaffected

Changes

sessionsList.ts: added getVisibleSessions(): readonly ISession[] to ISessionsList / SessionsList. The visible list (in display order, after filters/sorting/grouping; excludes items hidden behind workspace-group "show more" capping) is captured during update().
sessionsViewActions.ts: registered sessionsViewPane.openSessionAtIndex plus 9 keybinding rules. Handler resolves the active SessionsView, indexes into getVisibleSessions(), and calls ISessionsManagementService.openSession(). The keybinding weight is WorkbenchContrib + 1 so it overrides the built-in workbench.action.openEditorAtIndexN which also binds Ctrl+N on macOS.

for (let visibleIndex = 1; visibleIndex <= 9; visibleIndex++) {
    const sessionIndex = visibleIndex === 9 ? -1 : visibleIndex - 1; // 9 = last
    KeybindingsRegistry.registerCommandAndKeybindingRule({
        id: OPEN_SESSION_AT_INDEX_COMMAND_ID + visibleIndex,
        // Higher than WorkbenchContrib to override `workbench.action.openEditorAtIndexN` (Ctrl+N on macOS)
        weight: KeybindingWeight.WorkbenchContrib + 1,
        when: IsSessionsWindowContext,
        // Always use Ctrl (not Cmd on macOS) to avoid conflicting with Cmd+N view focus shortcuts
        primary: KeyMod.CtrlCmd | digitToKeyCode(visibleIndex),
        mac: { primary: KeyMod.WinCtrl | digitToKeyCode(visibleIndex) },
        handler: accessor => openSessionAtIndex(accessor, sessionIndex)
    });
}

@copilot Cmd+N is used for focusing various views in vscode, so I think it should use Ctrl regardless of OS

Good catch — switched to Ctrl+1..9 on macOS as well by adding mac: { primary: KeyMod.WinCtrl | ... } (which maps to Ctrl on macOS). 621a1a2

@copilot it doesn't work because another command is being invoked:

The conflict is with workbench.action.openEditorAtIndexN, which also binds Ctrl+N on macOS at the same WorkbenchContrib weight. Bumped the sessions binding weight to WorkbenchContrib + 1 so it wins (matches the pattern already used for the other sessions keybindings in this file). 5d0ab12

Pull request overview

Adds session-switching keybindings (Ctrl+1..9) to the Agents (sessions) window to quickly open the Nth/last visible session, mirroring common “tab index” navigation patterns while being gated to the sessions window context.

Changes:

Added getVisibleSessions(): readonly ISession[] to ISessionsList/SessionsList, capturing a “visible sessions” list during update().
Registered sessionsViewPane.openSessionAtIndex plus Ctrl+1..9 keybindings that resolve the active SessionsView and open the corresponding session via ISessionsManagementService.

Show a summary per file

File	Description
src/vs/sessions/contrib/sessions/browser/views/sessionsViewActions.ts	Registers command + keybindings and dispatches to `openSession(...)` based on visible-session index.
src/vs/sessions/contrib/sessions/browser/views/sessionsList.ts	Introduces `getVisibleSessions()` and tracks “visible” sessions during list updates.

 		const children: IObjectTreeElement<SessionListItem>[] = [];
+		const visibleSessions: ISession[] = [];



getVisibleSessions() is populated from the section/session data before it’s applied to the tree, so it can include sessions that aren’t actually visible in the UI (e.g. sessions inside collapsed sections, or sessions hidden by the tree’s Find-widget filtering). This will make Ctrl+1..9 open “invisible” sessions and misalign indices with what the user sees.

Consider deriving the visible session list from the tree model after setChildren() (e.g. traverse this.tree.getNode() in render order and collect only nodes where node.visible is true and the element is an ISession, skipping section/show-more nodes).

 	}

+	getVisibleSessions(): readonly ISession[] {
+		return this._visibleSessions;


This new getVisibleSessions() API is now used to drive keyboard navigation (Ctrl+1..9). Since there are already tests covering other logic exported from this file, it would be good to add coverage for getVisibleSessions()—especially cases like workspace-group capping ("show more"), collapsed sections, and Find-widget filtering—to ensure index-to-session mapping matches the UI.

Suggested change

return this._visibleSessions;

const sessions = new Set(this.sessions);

const visibleSessions: ISession[] = [];

const collectVisibleSessions = (node: ITreeNode<SessionListItem, FuzzyScore | undefined>): void => {

if (sessions.has(node.element as ISession)) {

visibleSessions.push(node.element as ISession);

}

if (node.collapsed) {

return;

}

for (const child of node.children) {

collectVisibleSessions(child);

}

};

const root = this.tree.getNode();

for (const child of root.children) {

collectVisibleSessions(child);

}

return visibleSessions;
