Change How You Use the Input Panel Tab
Besides choosing whether to show the Input Panel tab, you can customize it by changing the following default settings on the Opening tab in the Options dialog box.
You can choose whether the Input Panel tab appears on the left edge or the right edge of the screen. If you are left-handed, you may find it useful to move the Input Panel tab from the left edge of the screen to the right edge. You can move the tab either by dragging it across the screen or changing this setting on the Opening tab in the Options dialog box.
