An old post,I realise,but there's quite a lot wrong here, so this is for those that land here looking for the one-click solution.
This applies to a KDE version of Mint 13 Maya (Now,January '13).
I note that one can change to single-click behaviour in the file-manager Dolphin (only), but not as stated above.
The way to find prefs is not via edit-prefs any more, but a direct button on top row of dolphin, S
ettings, drop-down choice Configure Dolphin, panel Navigation.
However, there seems to be a messy BUG
, that this also
removes "Delete" from the context menu.(One wonders if this was inserted by some resentful ex-Windohs bugg-er in an act of insurgency?)
The option to remove "delete" in the context menu (or not) lies in S
ettings, drop-down choice Configure Dolphin, panel General, tab Context Menu.
Anyway, the edit config solution corrects this
Navigate to this hidden config file (editing does not require special priviledge) :
'save as' to a backup, just in case it is needed,
then add these lines:
and save. that.The new config will only apply to new instances of Dolphin etc.
Included there is the line to reinstate the delete option in context menu.

You won't find "tips" via the forum search,it responds rather snobbishly that the terms are too common. It can however be found by doing a site: search in one of the better-known search engines.
