App Studio - Status Bar
The Status Bar is displayed along the bottom of the App Studio window:
It is used to display status messages and other information.
For example, when you are working on a form, it displays the screen resolution you are currently working with and the position of the mouse pointer within the form on the right-hand side of the bar - see picture above. When writing Scripts, it displays the current position of the cursor (line and column) within the Script.
You can hide the Status Bar if you prefer, to increase the space available to the Workspace area, by deselecting the Show/Hide Statusbar option under the View tab on the Ribbon. Reselect the option to re-display the bar.
