Hey guys, I apologize in advance if this question was asked before.

But I was wondering, is there anyway to set the degree angle when you hold the shift key when dragging a new line in Photoshop, paint, or any program really. 

When you hold shift, the lines are always completely horizontal, vertical, or 45.  But I was wondering if you are able to set the angle manually somehow.  This would really help with getting that perfect step looking line.

Thanks,

Well, if you click once and THEN press shift the next time you click a "straight" line between both clicks points will be drawn.
however if you are needing to draw a precise angle the only way i can think of is just draw the straight line first and rotate it. for being faster you can transform it (ctrl + t) and check the angle in the info window.
remember that if you are working with pixel art you need to set the interpolation to nearest neighbour (edit-preferences-general-interpolation something). otherwise it will all get blurred.
hope that helps and you understand my suckable english.
