We’ve talked about how to repeat history commands with arrow keys in this previous post
You can use the up and down arrow keys to look up the commands you have used before, and press Enter key to repeat the commands you have executed before.
If an object is selected, hold down the CTRL key and press the up, down, left, and right arrow keys to move the object in the direction specified by the arrow keys, and hold down a certain direction key to move continuously. The moving distance of one click of the arrow key is not a fixed distance value, but is related to the size of the graphics window.
Sometimes this method may be useful when fine-tuning the position of the graphics is required. For example, when we arrange objects , if the position of a certain object is a little bit off, you can select the object, then hold down the CTRL key and use the arrow keys to move it, which is more convenient than using the MOVE command.
