Description

Click a valid location to place the caret on that location.

Press the right arrow key to move the caret to the first operand of the next instruction or to the next valid caret location (whichever comes first). The next valid caret position can either be a left or right branch rail or the next rung. The caret will not go up any branch levels.

If there are no more valid caret locations, the caret does not move.

Press the left arrow key to move to the first operand of the previous instruction or to the previous valid caret location (whichever comes first). The previous valid caret position can either be a left or right branch rail or the next rung. The caret will not go up any branch levels.

If there are no more valid caret locations, the caret does not move.
