Maybe i am not aware of these in ide,
but i find them quite usefull - especially with so little piece of code:

>>+=----------
mousewheel, numLinesToScroll read from system:
at Assist.cpp void AssistEditor::MouseWheel(Point p, int zdelta, dword keyflags)
int slines;
SystemParametersInfo(SPI_GETWHEELSCROLLLINES, 0, &slines, 0);
...
CodeEditor::MouseWheel(p, zdelta*slines, keyflags);

>>+=----------
when same char )]}" ahead_written - it's jumped over:
if((code==')'||code==']'||code=='}'||code=='"') && code==GetChar(GetCursor()))SetCursor(GetCursor()+1);
at CodeEditor.cpp: if(code >= 32 && code < 128 && count == 1) {


This is from sources v7936
