1,2,3    => selects region for query-replace.

5,6,7,8 => sequence causes region to be lost.

 

1. C-a (move-beginning-of-line) on the next to the last line:

-->  ( _nmPrmset.begin(), _nmPrmset.end(), _nmPrmset.begin(), ::tolower );

     }

2. C-SPC (set-mark-command)

3. C-e (move-end-of-line)

4. M-% (query-replace)

     The replace region is the next to the last line:

     ( _nmPrmset.begin(), _nmPrmset.end(), _nmPrmset.begin(), ::tolower );

5. Double-click left mouse on the "_" of "_nmPrm" on the next to the last
line

at column 5 to select "_nmPrm".

6. Middle mouse click then enter to insert in query replace:

    Query replace in region: _nmPrmset

7. Double-click left mouse on the "_" of "_nmPrm" on line 6 to select
"_nmPrm"

8. Middle mouse click then enter:

   Query replace in region _nmPrmset with: _nmPrm

 

Note the edit region of 1,2,3 is lost.
