Dear Eduardo,

 do you manage to move the blue trapezioid on the bottom? Put the mouse pointer over one of its edges and when the vertices are highlighted press the PgDown buttons until you see the lines emerging. You might want to practice with some other figures which do not overlap so tightly to understand how selection works.

Hi there

Many thanks, but unfortunately I must be dumb.  I read all the docs you suggested but I could don’t figure out how to bring the edge to the front, that is, how to go from

To

Hi,

 moving the reference frame of the picture is done with the arrow keys, to change the z-order of objects you have to select them (by moving the cursor over them) and then press ctrl+pgup or pgdown. 

if TeXmacs does not select what do you want, for example because several objects are superposed, you can use tab to cycle through them.

I would suggest also to give a look at Help->Manual->Creating technical pictures, for an overview of the main commands of the graphical mode, and  at this tutorial (which is slightly outdate, but still useful) https://www.texmacs.org/tmweb/documents/tutorials/TeXmacs-graphics-tutorial.pdf

HTH,

Hello,

First of all, I would like to thank the developers for releasing a stable beta version of TeXmacs. I have had no issues using it on a Mac M1—great work!

Now, to my question. I must admit that I am quite confused about which keys to use when running TeXmacs on a Mac.

In the YouTube video “Drawing a Simple Geometric Picture with TeXmacs” (timestamp 2:11-2:18), the figure was moved up and down. However, I am not sure how this was achieved. What keys should be pressed on a Mac? Is it just the down arrow key?

Additionally, I didn’t understand which keys were used to move the first parallelogram on the left to the back, making the edge in the front visible.

Is there any specific key or combination to select an edge or a face?

Apologies if my questions seem a bit naive.

Many thanks,

Ed
