One of the things I am always in search of, is a keyboard that will keep on working when its up to the family tools in metallic sawdust, aka swarf. Space is also a premium, and lately I have migrated this machine and my 3 cnc machines to a logitek k360 board, whose key sides are vertical as opposed to the usual tapered side keys, which allow a curlyque of cut steel to follow the key down, and then wedge it down. The K360 helps in that regard tremendously. I found an ACER keyboard that at first seemed to be ideal for such an environment, but one often picks up the keyboard and takes it to the machine so you can see what you are doing much more precisely when doing the setup to run a job. Unfortunately it has rows of extra "media keys" along the edges, and picking it up without pressing one of those is well nigh impossible. So its back to the K360, with its oddly placed pageup & pagedown keys which are normally used to raise or lower the head on a milling machine. It Just Works(TM) if I can get used to the compact layout. ;-) Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
