small red crosshairs ?

New User LibreCAD
iMac, 13,1 ICor I5 M.Lion 10.8.5
LC Version: master
SCM Revision: 2.0.0rc3

Compiler: GNU GCC 4.7.3

Qt Version: 4.8.5

Compiled on: Nov 13 2013

LC is behaving quite nicely here, so far.
I found the nice Intro Manual by Bob Woltz.
I Found  a couple tutorials too and am learning fast.
Some are a bit hard to follow, so I am still looking for more.

Just a few quick questions …

1) what is the the tiny cross hairs with a circle around it?
        It seems like it may be "the current placement cursor ?"
        how can this be used ?
2) I have seen references to using hatches.
        are these available anywhere, in LibreCAD?
        or does the user create them on the fly ?
3) The command line accepts commands like "rec" & "cir", what other commands does it accept and can I write combinations of them in one pass somehow ?

Thanks for any interest..
So glad to find this CAD program.

It's the "Relative Zero", can be set or lock via main menu:  Snap->Set relative zero position, or "Lock  relative zero position".

coordinates are displaced in absolute and relative coordinates.

You can use relative coordinates in command line by adding a leading '@' to coordinates. see:

Please help adding hatching to our wiki:

Basically, you select a closed contour of (lines, arcs, ellipse arcs), or a single circle, ellipse, then following instructions by : Draw->Hatch, and select your pattern in a pop up window.

Again, please help adding command line information to our wiki:
