Well, yes and no.

Indeed, that combination (CTRL+KEY_UP/DOWN/LEFT/RIGHT) is convenient for drawing orthogonal lines.

However! It's not limited to lines only.

It just provides a handy way to specify a coordinate. In other words, it allows to define a point that is related to the current position of Relative Zero - one is located in direction specified by KEY_.. on distance specified by entered value.

Therefore, such way will work for ALL places where the input for the coordinate is expected (say, center of circle etc.)
