Apple - How to set to open folder with enter in finder?

Any person new to Apple and Mac would find lot of things un-intuitive or just forced on the user, w/o any options to change it. Or it might be that just many of us had their first experiences on Win/Linux systems.

But just found this plugin to finder XtraFinder which among lot of other options allows you to ENTER/RETURN to open a file.

Feeling a lot relieved now! Hope it helps.

As I know you can not set it to enter in a normal way (but maybe exist some tricky way) but you can change open shortcut by going to System Preferences > Keyboard > Keyboard Shortcuts tab from the left window choose Application Shortcuts and press + to add new shortcut then find Finder in Application and choose Open in Menu Title and press any desired shortcut in textbox.

PresButan (Mac OS X 10.4.x-10.7.x): An idiotically named solution to a spectacular UI oversight (rather apropos, eh?).
It also lets you use either the backspace or delete key to delete files.

I can confirm it works (just installed it). Apparently it leverages the accessibility system and uses a daemon to catch the return events.

If you are on 10.3-10.5, you also have the option of using ReturnOpen.
