+ \class PyConsole_Editor
+ \brief Python command line interpreter front-end GUI widget.
+
+ This class provides simple GUI interface to the Python interpreter, including basic
+ navigation operations, executing commands (both interactively and programmatically),
+ copy-paste operations, history of the commands and so on.
+
+ Here below is the shortcut keyboard boundings used for navigation and other operations:
+ - <Enter> : execute current command
+ - <Ctrl><Break> : clear current command
+ - <Escape> : clear current command
+ - <Up> : previous command in the history
+ - <Shift><Up> : move cursor one row up with selection
+ - <Ctrl><Up> : move cursor one row up without selection
+ - <Ctrl><Shift><Up> : move cursor one row up with selection
+ - <Down> : next command in the history
+ - <Shift><Down> : move cursor one row down with selection
+ - <Ctrl><Down> : move cursor one row down without selection
+ - <Ctrl><Shift><Down> : move cursor one row down with selection
+ - <Left> : move one symbol left without selection
+ - <Shift><Left> : move one symbol left with selection
+ - <Ctrl><Left> : move one word left without selection
+ - <Ctrl><Shift><Left> : move one word left with selection
+ - <Right> : move one symbol right without selection
+ - <Shift><Right> : move one symbol right with selection
+ - <Ctrl><Right> : move one word right without selection
+ - <Ctrl><Shift><Right> : move one word right with selection
+ - <PgUp> : first command in the history
+ - <Shift><PgUp> : move one page up with selection
+ - <Ctrl><PgUp> : move one page up without selection
+ - <Ctrl><Shift><PgUp> : scroll one page up
+ - <PgDn> : last command in the history
+ - <Shift><PgDn> : move one page down with selection
+ - <Ctrl><PgDn> : move one page down without selection
+ - <Ctrl><Shift><PgDn> : scroll one page down
+ - <Home> : move to the beginning of the line without selection
+ - <Shift><Home> : move to the beginning of the line with selection
+ - <Ctrl><Home> : move to the very first symbol without selection
+ - <Ctrl><Shift><Home> : move to the very first symbol with selection
+ - <End> : move to the end of the line without selection
+ - <Shift><End> : move to the end of the line with selection
+ - <Ctrl><End> : move to the very last symbol without selection
+ - <Ctrl><Shift><End> : move to the very last symbol with selection
