How to draw tactical lines properly?

I can see in videos how they draw any amount of lines and circles with the mouse, but when I draw the second line with right mouse button the first disappears.

I guess you can do that in many chess programs, for instance it is possible in the free program SCID (with CTRL + drag):

I guess they do it somehow without additional programs, because the lines look exactly like Lichess

@Puzzles11only, no, the rating does not unlock the possibility, it will always be available, whether you are 900 rated or 3000 rated. If you want to draw arrows, right - click on your mouse and drag to draw one from a position on the board. If you draw the exact same arrow on the same position twice, it will disappear, the same will happen if you left - click.

If you would like to draw coloured arrows, here are some:

right - click + drag = green arrow

CTRL + right-click + drag = red arrow

ALT + right-click + drag = blue arrow

CTRL + ALT + right-click + drag = yellow arrow

As for circles, simply just right-click on your mouse once.

Hope this helps!

@TotallyReckless bro look , thi s guy draws 3 lines without disappearing lichess.org/variant/racingKings
PS thanks by the way for that info

Yes, because he did not left-click or redraw the exact arrow on the same position on the board.

@TotallyReckless I didn't either, yet the arrow disappears anyway
