%%%According to section "Selected elements after switching select mode" in http://wiki.blender.org/index.php/Doc:2.6/Manual/Modeling/Meshes/Selecting, Ctrl LMB on a selection mode (vertex, edge, face) button that is ascendent should select objects that are "touching" the selected object. While this does happen, sometimes extra objects are also selected. For instance, a cube vertex should only have three "touching" edges when ascending. However, selecting a vertex and pressing Ctrl LMB on the edge selection button will sometimes select more than three edges depending on which vertex was selected.

Steps to reproduce:

Start default cube scene
Tab (edit mode)
A (deselect all)
RMB vertex nearest camera
Ctrl LMB edge selection button

Notice that all expected edges are selected, but also all top face edges are selected.

Another example with different outcome:

A (deselect all)
LMB vertex section button
RMB vertex beneath vertex in step 4 (bottom edge vertex nearest view)
Ctrl LMB edge selection button

Notice that all edges are selected.

Another example with correct outcome:

A (deselect all)
LMB vertex selection button
RMB vertex on the top-left
Ctrl LMB edge selection button

Notice that the correct edges are selected.

Also, ascending from edge to face mode does not work for any selected edges unless a complete face would be formed with the edges.

%%%Never heard of this feature...

Campbell: user presses CTRL on the buttons for select modes? That's all a bit dodgy imho. Select mode switching as it was (losing individual vertices if you go to edge, for example) is predictable and acceptable. Hiding button features like this we should try to prevent.%%%
