Enter key on Mac OS X renames files instead of launching [duplicate]

Enter to open a file in Finder

On my Mac when I hit the "enter" key on a file on my desktop or in the finder, it enters the "rename file" mode.

1) How do you actually "launch" or "open" (i.e. double click) the file with only the keyboard? In Windows, the Enter key does this. 2) Is there a way to map the Enter key to do this in Mac instead of rename?

Honestly, it makes little sense to me. I mean, how often do you rename something? Once, maybe. How often do you open something? Lots and lots of times.

Cmd-O. Enter has been the command to enter rename mode for a loooooong time. At least since System 7 in 1993.

That bothered me, too, when I switched to Mac, but after some years of use and renaming lots of files in Finder, I appreciate it over pressing F2.

You can also open any file in the Finder by pressing cmd-down (the apple key + the down arrow). It also works for folders, too. This is intuitive if you think about it this way: cmd-up navigates up one level in the hierarchy of your filesystem and cmd-down navigates deeper. If it's a file, going deeper opens the file.

When you are using the Desktop, you are actually using the Finder.

So select the Finder's File menu to see various shortcut keys you can use to perform various commands on the selected icon.

For more advanced / different keyboard shortcuts use the keyword shortcut to look for information in Mac Help.
