SECEditController::m_pLastCmd
SECEditCommand* SECEditController::m_pLastCmdHolds a pointer to the last command that was generated by the last typing command. Used when a character is typed in the OnChar handler. When possible, Objective Edit groups the characters together into a single command that may be undone with a single undo operation. For example, the following line:
this is a test
would be undone as 7 operations; one for each of the 4 words, and the three spaces.
