Can we have the number of (tools (?) selecteds like segments arcs etc ...)
I have found that click on an empty space unselect all...
Why : say i want draw a square during a session yet started (so some things existing on the canvas ( screen) ?)
I draw a line
I want select it (click on the empty screen by security) then select it then CTRL D (similar than Clone Paste in place)
Now i want to be sure that there are 2 lines existing (so number existing somewhere will be cool )
Call Rotation
Now i want to be sure that I Click one extremity ! Pressing Right for have Red disc don't work that give another point of rotation not the extremity
Clicking very near the extremity is not sufficient sometime that take it, some time not! How to force it ?
So I am perplex

(of course i made hundred of tests! ) There is a trick ? different layer ?...
Concept was A line - Copy Rotation by an extremity, Mirror the 2 lines by the diagonal = a square

That works fine when i success to click the extremity!
As you see this time i had not clicked the extremity! And seems there is a maximum zoom!
And I have not the Snap magnet ?

EDIT: reading the MANUAL SEEMS SHIFT IS THE KEY
Discover also that a dedicated Forum White Rabbit is existing! I am the only one member !
Do you prefer that I post here or there ?
PS I don't record the proove of the sqaure by diagonal, middle of it then draw a circle passing on the 4 Square's verticies!
