Hello,
In the Artboards panel, when you edit an artboard name, you can hit tab to key into the next artboard to change its name without having to reach back to the mouse to double-click the next artboard name to change it.
However, in the Export for Screens window, in the artboard section, if you hit tab when editing an artboard name, the Select: > All radial button becomes highlighted.
This is not the behavior I expect in this context, and is inconsistent with the behavior in the Artboards panel.
As a compromise, perhaps we could have conditional behavior, where, if you're editing an artboard name in the Export for Screens window, hitting tab goes to the next artboard name. Otherwise, tab will just move to the settings on the right.
