Tip #9: Lock: Many of my carefully prepared Notebook lessons--"Notebook" is the software designed for the SMARTboard--were pounded to mush as students tried to drag words into the right category—a condition called “stuttering finger.” The student touches the text box; the finger slips and taps again. This double-click opens the text box for editing, whereupon, the next slip rearranges the order of the letters till the lesson is unintelligible. The cure: Lock. Select the text box, pressing on the downward-pointing triangle to choose “Lock.” If you prefer, use Command-l. In the case of a text box that needs to be placed somewhere else on the page during the lesson, choose “Allow move”--no keyboard shortcut for this. Now the words in the text box cannot be changed until you use the same pull-down menu to “unlock”--or Command-u.
