I am new. Usually when I am in command mode (I mean when I pressed ESC), the cursor shape becomes a block, it is well that when I press `i' or `a' the cursor will become a bar at the left or right side of the block. But here is a problem, when I want to enter something like:
(test) I will enter the parentheses first, then I need simple key stokes to back one letter like: control oh or control oi it depends on whether the cursor is at the end of the line. Is there any better way to do so?
