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,
Settings, 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
Settings, 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) :
/home/mint/.kde/share/config/kdeglobals
'save as' to a backup, just in case it is needed,
then add these lines:
[KDE]
ShowDeleteCommand=true
SingleClick=true
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.
