Some of you who have been Mac users for many years may have forgotten these. I think the keyboard shortcuts can be extremely helpful, especially if you mouse is acting up. The Apple branded mice can be a nightmare. I also have a recommendation for an inexpensive but highly functional mouse to use with your Mac desktop or laptop, if desired.
Mac Keyboard Shortcuts
Cmd + C = Copy
Cmd + V = Paste
Cmd + Z = Undo (especially when typing)
Cmd + A = select all (often prior to deleting or copying)
Cmd + P = Print
Mouse recommendation: This one won’t let you down. It comes with a small dongle that you plug into a USB port. It is micro sized and does not get in the way of your other accessories. I also provided a wired selection in addition to the first mouse which is wireless.
