It's version 10.7.5; 2.3 GHz Intel Core i5; and 2GB memory at 1333 MHz DDR3. I have a certain .doc file that contains text only, a couple of different sizes, all in Helvetica (or else Arial) except for a few lines where I have a few cursive fonts, at least one type of these fonts I added to the computer. That may be the origin of this problem. This is the 3rd time all text has been "reverted" to some unfamiliar font upon opening, with about 10% being unreadable gobbly-gook. In the past it has corrected, the last time it corrected by opening a copy of the document off of a thumb drive. This time I can't get it to correct.
OK, which is the Command key? This is a Dell keyboard. The Windows icon (waving window symbol)? Or Ctrl? Or the one with an icon that looks like a document with a cursor?
It looks like the Windows symbol was it. It took me into User Utility (I think it was called). I decided against reverting to a previous time because then I'd likely lose work I've done since that time. Not worth it. I'll keep this fix in mind though in case I want to one day. Thank you.
Well, Time Machine is what came up automatically, through User Utility. There was not a 'Recovery HD partition' message, or 'Disk Utility' message.
I have the steps alright, but now I don't see what would be the 'option' key. What would the key be that has a picture of text with a cursor? I don't want to be experimenting without knowledge.
Thanks for the chart on key meanings. I restarted holding Ctrl + R but the operating system came up naturally - no affect. I think I'll let this go and just not combine any uncommon font work with other data on the same document in the future. Thanks.
