# In Draw, alt centres an object but also overrides snap. Can another key be assigned to one of these?

I frequently want to draw a circular arc from a given centre with a given radius. I can use alt to snap to the centre, but then I cannot snap to the point at the end of the desired radius because alt is overriding the snap. It seems that ctrl has no effect on the drawing, so is there a way to reassign it, so that pressing it simultaneously with alt (and shift for circle) will retain the snap settings? Any other suggestions welcome!

@pja37, It's not as hard as it looks.

Alt has a double function here.

1. Choose menu Shape - Insert - Basic Shapes - Arc.
2. Drag from the center point of the final arc (without Alt) until reaching the desired radius, and release the mouse button (you will get an ellipse half the expected size of the arc).
3. Press Alt and move the mouse (and you will get the ellipse in the expected size).¹

Tested with LibreOffice 6.4.7.2 (x86); OS: Windows 6.1.

¹ If you release Alt at this point you will get the ellipse at the original half size. Could press and release Altas many times as you want; as soon as you move the mouse, the ellipse size will change.
