avatar movement

On the MAC, can someone tell me what command I use to make my avatar sit down? I am a newbie but have searched every help resource I have found. Thanks.

I would try ctrl clicking, since that is the equivelent of right-clicking on the pc, that should bring up the actions menue.

you have a lot to learn about SL. If you just want the right-click and sit option (which doesnt always really "sit" then right clicking in SL is CMD+click not CTRL+click.

I bough a cheap Logitech two button mouse with the twiddly scroll wheel. On sale for about $10. Plugged right in and worked with no problem.
Right click on yer AV and get a 'circular menu' with some commands for changing clothes and other things, right click on the ground, not on yer AV and get another 'circular menu' with the sit here command and some others. If you right click on another person's AV you get a 'circular menu' about making friends and so forth.
I'm a new guy too. I hope this helps.

It's a Three button mouse, left, right and scroll wheel. I got it for surfing the web but it works pretty good for SL, still $10.
Those 'circular menus' are called 'target menus' click on different things and get different sets of commands.

Actually we call them Pie Menus
