Back when I was a Windows user in another life, I faintly remember a nice shortcut when browsing a directory: type the first letter of the file name you want to be highlighted, and keep pressing to iterate through the rest of the files that start with that letter. So for example if 10 files were listed that all started with the letter 's', I'd just keep pressing 's' to go through each file.
However, something else happens when I do the same in Finder on Mac. It looks like it's almost about to do that same thing Windows does, but when I press 's' repeatedly, it only finds one or two files out of say the 40 I have in the current directory that start with an s. So I'm not exactly sure what kind of behavior that is, if it's a type of shortcut of it's own, but for now it just seems random to me.
Any idea how to do the Windows-like trick, and what Mac currently does when I try that?
