In Windows, we can select a file/executable in Explorer and on pressing Enter with the keyboard, the file/executable is opened. Is this feature available on Mac OS? In Finder, if a file/executable is selected with the mouse and then we press Enter, it wants to rename the file.
PresButan 1.4 worked for me on Mac OS Mojave (http://briankendall.net/presButan/index.htm). I had to manually add it to System Preferences -> Security and privacy -> Privacy -> Accessibility -> Allow below apps to control your computer
