GoalStream provides a number of commands for controlling the zoom level.
Your basic zoom commands are Zoom In (K) and Zoom Out (J).
Zoom-To-Fit (vv) modifies the zoom level so that all tasks in your project become visible on screen. This works no matter the size of your project.
Zoom-To-Fit Selection (vs) works in much the same way. However, instead of making every task in your project visible, this command ensures that the selected tasks (both primary and secondary selections ) are visible.
Check out this tip to learn how to use the Zoom-To-Fit Selection command to focus on the context surrounding a task.
Reset Zoom (vz) sets the zoom to the default level (1x).
Reset View (vr) does the same thing, but additionally resets the scroll position back to the inital value.
