### Surface Image-Window Clicks ###
-------------------------------------------
(1) Left-Click: Select vertex, add to 'marked' list

(2) Middle-Click: Unselect one vertex

(3) Right-Click: Clear all selections/marks (undo clear: Cmd-z)

(4) Shift-Left/Middle/Right-Click: Rotate/Translate/Scalebrain
      (also: Rotate -> arrows, Translate -> Shift-arrows)
      (also: In-plane Rotate -> Ctrl-Shift-L/R-arrows)

(5) Ctrl-Left/Right-Click: Zoom/Unzoom around clicked point

(6) Ctrl-Middle-Click: Dump voxel time course

(7) Left-Double-Click: Raise tools interface window

(8) Middle-Double-Click: Popup name of annotation region

(9) Right-Double-Click: This help

(10) Shift-Left-Click: Sample sphere img(s) at this vertex

### Volume-Image Window HotKeys -- Single key ###
---------------------------------------------
# interface size
F2 -- basic interface   (Mac=fn-F2)
F3 -- large interface   (Mac=fn-F3)

# rotate,scale brain (interface win: add Mod)
R/L arrow           -- rotate around vert axis
up/down arrow    -- rotate around horiz axis
Control-Shif-R/L arrow  -- rotate in plane
Shift-R/L arrow    -- translate right/left
Shift-up/down arrow  -- translate up/down
plus (+)              -- scale up 1%
equals (=)          -- same as plus
minus (-)            -- scale down 1%
D-key (d)           -- re-select prev. selected (get over annot)
