My history with the Mac goes back to early college days, now over 15 years ago, so that historical tidbit should put your age calculations into overdrive. As with most Mac users I preferred to use a computer to get stuff done rather than tinker around the complexities, and foibles of a Windows PC. I don’t remember when exactly, but somewhere around 10 or 12 years ago I came into possession of a multiple clipboard app. If you don’t have one, get one on my recommendation.
A multiple clipboard manager simply grabs and stores whatever you copy or cut onto the Mac’s clipboard (which is limited to one piece of text, or graphic, or photo, or whatever at a time) so you can paste it again later without having to find the original, copy it again. Among the better versions of a multiple clipboard manager are PTHPasteboard Pro and CopyPaste Pro, either highly recommended.
Both are stellar tools almost guaranteed to improve your efficiency and productivity, especially if you copy and paste frequently during your workflow. However, if money is an object, and you’d prefer a simpler tool, try xClipboard first. It’s a barebones multiple clipboard manager that resides in the Mac’s Menubar which makes it easy to access.
Whatever you copy on your Mac gets stored in xClipboard. Then, when you need the same text snippet, or image, or graphic, or photo or whatever again, click the Menubar icon and select the item to be pasted into a document.
There’s not much else to xClipboard, either. Click on the Menubar icon, select the item to be re-copied and pasted, and paste it wherever you need it. Copied items can be sorted and searched and organized by type (images, text, photos, etc.). I prefer the extra functionality and library synching of PTHPasteboard (the slide out window of copied items is the best; no clicking) but xClipboard is much simpler to use and far less expensive.
