Am I the only one with this annoyance, because I can't find anybody else on Google.
I'm in Library, I hit Command-F (on Mac) to do a text search, I have a several 4-digit numbers to type in. For some reason a few seconds after I start typing, all the text is selected. So if I don't notice and hit the arrow key to unselect, it deletes what I typed before! This has irritated me for years! Why does it do this? I often have a series of 4 digit numbers to type in to pull up photos somebody has ordered, and I have to either type fast enough so it doesn't happen, or stop and wait for it.
Okay, so following on Johan's lead, I googled it for mac without mentioning Lightroom, and found a reference to Mac Preferences/Keyboard/Text, where you can add auto-replace shortcuts. The only one in there was `omw` which it would replace with `on my way.` Must have been a default, because I didn't add it myself - and I don't see how that should cause problems when typing a 4-digit numbers, but I removed it. And right now, it looks like that may have solved the problem!
