How to avoid double clicking? [duplicate]

Is there a setting, key combination or similar to open a folder/subfolder in Finder with a single mouse click ? I need a general solution which works on any folder in effort to minimize needless clicking ... that tiny triangle aside the folder icon will work yet its just too small and only appears using list view ... inspired by same behavior on osx inside a browser to hold down command key and single click a web link ... forcing users to double click is so 20th Century

Is there a way to enable this on macOS (High Sierra or higher)?

On ubuntu this single click preference is a simple setting ;-)

I agree with you on double click. I bought a multi-key mouse. I assign a key to double click. Not a perfect or free solution, but better.

This is not possible natively in macOS

While you may be able to assign a double click mouse action or a keyboard shortcut (CommandO) to your mouse but using something like AppleScript (i.e this answer and this answer) or USB Overdrive there is one main obstacle that must be overcome - the lack of hover to select.

However, there is an App called DwellClick which is designed to automate your mouse clicking for you. They have a feature called "point to click" which will select an item if you leave your pointer on it for a specified amount of time. After which you can click with a reassigned mouse button to emulate double click.
