Lol, it was half joke im sure you gathered. There isnt really much of a possible shortcut to doing "move the cursor 1 character to the left".

The optimization isn't in "move the cursor 1 character to the left", it's in "move the cursor 1 character to the left without moving your arm".

But there are shortcuts for things like moving cursor to next indentation block or to closing or opening brace.
