Setting Mark Before Moving Point on `w3m-next-anchor'?

[David Hansen <david.hansen@xxxxxxx>]

Hello,

kind of a feature request (I can implement it myself if wanted).  Just
wanted to ask what you think:

From time to time it happens that I want to go back to the buffer
position before I hit TAB or `}' (`w3m-next-image').  This can be quite
cumbersome if point moved a large distance.

Do you think it makes sense to set the mark before several moving
commands?  Should it be customizable (maybe some threshold)?
