When creating a polygon selection, is it possible to create 45 degree selection by holding down a key like SHIFT? Sometimes it is difficult to create straight lines by freehand.

Thanks.

Is there a special way to use the ALT key because when I tried selecting with the ALT key, the lines go way past my cursor and I can't seem to control where it should be the next point. Please advise.

I guess I am looking for a functionality similar to Photoshop when using the Pen tools. Is this possible?

ALT key force the line you are drawing is aligned to 45-90-135-etc... It works as expected in my tests.
No Photoshop Pen tools are available.
