How erase a line(s) with just one click ?
not works here


All functions can be pressed on the screen but very speedy with SHortCuts!
T + F + Ctrl+2 + Shift + Click
aTtach  + Face + SHIFT + Axe(s) +  Click (Shift is a trick for keep the creation mode but this invert it)

you must know the axe of it : easy because there is a tripod RVB on the bottom righ of the screen
So Axe Y [b]key on the screen or (CTRL + 2) because shortcut y is yet for other thing!
