You might want to think about road speed if you are not going through the gears sequentially in regards to subsequent engine revs.

And the load on the clutch as a result.Andy
Same on the way down, unless as you say you drag the clutch up to speed rather than blipping and matching.
1) Yes. You can inadvertently put pressure on the change mechanism (selector fork) which can cause premature wear.
2) No. My instructor was an advanced driver and taught me to skip gears when changing (mainly up but also going down when the situation was suitable). I still do this today when driving a manual box. It's simply getting the engine and road speed to match. On a clear road pull away rapidly in second and then go into fourth without thinking about it. Also do this on the bike.
Obviously this depends on the vehicle; four, 5 or 6 gears and road conditions.

I have a question about manual 'boxes specifically Mercedes manuals (sorry for the thread hijack!)
How do they work? Never been in one but they have four pedals how do you do a hill start? Put it in neutral hold brake pedal??! It must be like rubbing your stomach and tapping you head shirely?

1) does it damage the gearbox if you lightly rest your hand on top of the gear lever?
That's a myth spread by driving instructors so that you hold the steering wheel with both hands!RDRR said:

You only press the fourth pedal to engage the handbrake, you pull an umbrella lever to take it offHow do they work? Never been in one but they have four pedals how do you do a hill start? Put it in neutral hold brake pedal??! It must be like rubbing your stomach and tapping you head shirely?
1) depends how hard I suppose, some gear levers which you push down to select reverse gear would presumably be moving something in the gear selector when ur pushing down on it.. also, if u lean in a particlar direction u might pull out of gear slightly.. leaning on the clutch pedal is a more common problem!
2) generally this is ok, as you say a technique taught on advanced driving, however on some vehicles this can (apparently) be bad for the syncro, but u can help by double clutching.

Another question on manuals, clutchless changes, in some circumstances when going up the box I find it possible at relativity low revs to slip into gear without using the clutch at all.
Why does this happen?
Are there any other circumstances where this could happen (down shifts)?
Do you have to declutch first, when taking the car out of gear?

you can pull the car out of gear without the clutch, then it's just a case of matching the engine speed with the road speed appropriate to the gear you're going to select.Why does this happen?

I wouldn't do it all the time, to save clutch wear, but if you've never messed about with it as a technique, do it, it's handy to be able to do in case your clutch gives up the ghost when you're out and about and don't want to get stranded.
