Yes, please do!

Sounds good, please remove the "::" so things compile.

This is something you will want to figure out on your system to see if you can
get the function keys working. There is a work around for Apple builds where we
look for \033OP for F1, so if you search for "\033OP" in the sources you can
see the work around that we used to map non-standard function keys to the
correct key definition.
If you type "infocmp" at your unix command line you should get a dump of the
current key mappings and you should see what your function keys are mapped to.
On my system I see:
kf1=\E[11~
kf2=\E[12~
etc...
If you place a breakpoint on the following line (IOHandler.cpp:1686):
HandleCharResult key_result = m_window_sp->HandleChar(ch);
then press F1 on your keyboard and see what characters come through, you can
see what your function key is coming through as. It is probably an escape
character followed by a few keys. Then you can either figure out how to enable
function keys on your version of curses, or handle the keys like I did for Mac
in the #if defined (__APPLE__) code that intercepts and remaps keys.
As a work around, you can use the right and left arrow keys to bring up the
menus so you can select LLDB->Exit.
Most menus don't work at the moment except for "LLDB->Exit", but I will be
hooking them up soon.
A few things to try in "gui" mode:
Press TAB to change the active window. The active window has the solid white
border around it. Each window can handle keys differently.
when the source view is selected press the following keys:
s - step in
n - step over
o - step out
k - kill
d - detach
b - set breakpoint on selected line
UP/DOWN - move line selection around so you can set breakpoints and run to that
line
SPACE - set one shot breakpoint on selected line and and run to that line
, = page up
. = page down
When the "variables" view is selected:
UP/DOWN - use the arrow keys to change the selection around
RIGHT - expand current item
LEFT - unexpand if the item is expandable, else select the parent if not
expandable
x - format value as hex
u = format value as unsigned
o = format value as octal
, = page up
. = page down

Yep, I have about the same thing and we will need to work these things out and
fix them.
