[arni2033]

>>>   My Info:   Win7_64, Nightly 49, 32bit, ID 20160526082509
STR_1:
1. Open scratchpad, type/paste there "heLlo woRld"
2. Select "eL" in "heLlo" with mouse (from left to right!)
3. Hold Ctrl+Alt, then select "oR" in "woRld" with mouse (from right to left!). Release Alt and Ctrl.
4. Press Shift+Right to change selection

AR:  Selected strings - "eLl" and "oRl"
ER:  Selected strings - "eLl" and "R"  (See Note 2)


STR_2:  (reference of good behavior)
1. Open scratchpad, type/paste there "heLlo woRld"
2. Select "eL" in "heLlo" with mouse (from left to right!)
3. Hold Ctrl, then select "oR" in "woRld" with mouse (from right to left!). Release Ctrl.
4. Press Shift+Right to change selection

AR:  Selected strings - "eLl" and "R", just as expected  (See Note 2)


Notes:
1) �aret in selection range is placed at the right if selection was made from left to right, and at
   the left otherwise. That's what I call "direction" (this is how I understand this as a user).
2) Extended expectations:  Consistency, i.e. either X or Y
 X) If Ctrl+Alt selection tries to help user by guessing direction of selection range,
    Ctrl selection should also use the same logic and always set left-to-right direction for range.
 Y) If there's no intended additional logic, Ctrl+Alt should respect direction of text selection

Note: reproducible in other codemirror instances...
