For Editing text blocks and labels:
– OptionClick on one text block or label to switch to that tool. OR, faster: create a keyboard shortcut to activate the tool.
– Select All - all texts or labels get selected once you've activated the specific tool.
– TripleClick the text or labeltext of the first label or block to select all of the existing letters in that element. [DoubleClick for an individual word]
– Begin typing or pasting. It replaces automatically.
– CommandEnter will close that label or text block.
– Move on to another one since they are all selected already.
This method speeds you up a lot since selecting tiny labels or text blocks individually gets tedious.
