The reason I'm posting this here is because someone posted a while back about their wrists and arms starting to hurt after long sessions building their route, I'm afraid I could not find the post, hence this one. Moderators, please move this thread if you feel it's in the wrong place. And I hope that I have not broken any forum rules (I did check but I could not see anything).
OK I'd better get this out of the way first. This is not an advert, the only reason I'm posting is because I thought it may help others who get uncomfortable while using RW for extended periods. And I'm not affiliated with Belkin at all. It's just the product I purchased, and although it's early days I'm rather pleased with it. There are other products that do the same thing.
I'm referring to the rather bizarre looking Belkin n52te:

It's a programmable mini keyboard with build in thumb pad. I brought it because using the arrow keys to move the camera around while route building is a right royal pain. It works OK while driving. But when in the world editor, I expect to be able to have my right hand almost permanently on the mouse and my left hand controlling everything else. Reaching across my body to maneuver the camera started to hurt my left shoulder. I'm now able to control the camera with my left thumb. And my left arm and hand now sit in a much more natural position.
In addition to the camera, each key can have a single character or a macro of characters assigned to it. The whole unit can go into one of three modes, meaning that key mappings can be toggled. For example, I have programmed the first mode for driving trains (though there may not be enough keys if your driving a steam loco and doing the fireman duties yourself). The second mode I've used for shortcuts available in the world editor, can't think of what to use the third mode for yet
Shame there is no left-handed version, but like I said, there are other products.
Hope someone finds this useful,
Shad.
