I’ve always been a PC person but switched to Mac about 2.5 years ago when I started my current gig. It was surprisingly easy to make the switch and I really had no complaints.
Except one:
I missed the “Home” and “End” button functionality. When in Windows and editing a file with multiple lines of text, these buttons will take you to the start or end, respectively, of the line on which the cursor sits. On a Mac, these buttons take you to the start or the end of the file. Bart no like.
Since my switch, I’ve always hated this. I have a coworker who consistently tells me that the same result can be had by using the up/down arrows on the keyboard. “Works every time,” he says. Well, it works every time there is only one line of text, otherwise it just moves the cursor up or down the lines. Not helpful and he still tries to tell me this when I bemoan my fate.
Last Friday, another coworker clued me in, and I’m really surprised that it’s taken this long for the information to get to me. So, allow me to elucidate:
When your cursor is on a line of text and you want to jump to the start or end of that particular line, then click CMD+ (left arrow, right arrow), respectively. Simple, really, and I’m again surprised that no one told me sooner. Same functionality as the Home and End buttons on a PC.
Genius! Now, I’m back at 100% effectiveness.
