As a previous user of PagePlus I do my best to adjust to the differences I find in Publisher but one thing really tries my patience and irritates. In Pageplus just the movement of the cursor ensures that the function automatically and every time, without fail, switches easily between Move and Text Entry modes as it enters or leaves a text frame or moves over a picture or drawn object.
In Publisher the cursor does change from Move to Text entry cursor. Often only after you have cllicked again inside the text frame. To get it back to a Move cursor you must either click on the move icon or press V, even so this may only work if you leave the page and sometimes afterwards only if you tap again on the artboard. This breaks the workflow like nothing else.
