What's the most obscure, least known command that you know and will share?

hmm... I don't remember where I got this exactly, but sure from internet.
Anyway kudos for developers even if they included this for testing purpose

had to retire my tablet, but have the puck hanging on the wall

I have a tablet (digitize board) and still use a 16-button puck. I have buttons programmed for endpoint, intersections, zoom window, zoom previous, etc.. I don't use the digitize board for actual digitizing and use it so my puck works. I prefer the puck rather than the regular mouse while using autocad.

a 16 button puck was the best and fastest. 16 commands on one hane & keyboard shortcuts with the other. now only if they made a 16 button mouse with a wheel. I never used the tablet for the menus, only the puck.

I agree! 16-button puck is great for using autocad

I use;

ssx - similar to qselect, but at the command prompt
PSLTSCALE - Controls the linetype scaling of objects displayed in paper space viewports.
REMEMBERFOLDERS - When you start AutoCAD by double-clicking an icon, if a Start In path is specified for the icon, then that path is used as the default for all standard file selection dialog boxes
MEASUREMENT (loads acad or acadiso files at startup) 1-metric 0-imperial
TRUSTEDPATHS - Specifies which folders listed in the Support File Search Path have permission to load and execute files that contain code.
SYSVDLG - setvar dialagoue

(vlax-dump-object (vla-get-files (vla-get-preferences (vlax-get-Acad-object))) T) ;shows all paths set in autocad, takes 20 seconds to run

WSAUTOSAVE - Saves changes you made to a workspace when you switch to another workspace
SAVETIME - Sets the automatic save interval, in minutes. The current drawing is saved to the path specified by the SAVEFILEPATH system variable.
APPAUTOLOAD - 0 removes apps from autocad startup, makes startup faster, will not affect loaded lisp routines or mnu setup.

NEW ~ for 2015 and 2016 (numbers are my preference / default)
CURSORBADGE - 1 Badges are little images that appear at the upper right of the cross-hair pick box.
COMMANDPREVIEW - 0
SELECTIONEFFECT - 0 Selection preview allows you to see what object would be selected if you completed the current selection action.
SELECTIONPREVIEW 2 - On when a command prompts for object selection.
PRESELECTIONEFFECT 0 - Dashed and thickened lines, no solid fill for faces.
PREVIEWFILTER 0 - Excludes nothing.
HIGHLIGHTSMOOTHING 0 - Turns off anti-aliasing effect on object selection highlighting.
LINESMOOTHING - 0
SYSVARMONITOR - keep an eye on critical system variables that seem to create havoc when they change.
STARTMODE 0 - turns off the start tab
LWDISPLAY off - turns off line-weights of lines

That's all for now, if I think of any more I'll post them.

Dear Jmctamney.... insteade of Qselect i use selectsimilar(ss)... vary interesting command.

I fell in love with SelectSimilar back when I was using Map and was really irritated when it was removed from the product (though it was still in ACA and AMEP, I believe). A friend wrote a lisp routine that saved me, until vanilla AutoCAD picked up the functionality in r2011.

Haha, I'll admit that I didn't remember the actual release offhand, I looked up the last AutoCAD Tips and Tricks article I wrote, because I knew I'd referenced it there: https://www.augi.com/library/tales-from-the-dork-side

My favorite tips included in the link above are:
Reference Manager application for batch repathing
DVIEW TWist
Using existing layouts as templates
Filtering selection sets with LayIso, QSelect, Filter, SelectSimilar
Adding custom words to the spell check dictionary
Xclip (and the invert option)
Keeping palettes from docking
Keyboard navigation (between files, programs, layouts & viewports)
The importance of system variables
