autoflush : if you turn autoflush on, after each disabling or clearing an event using the 'events' command, all the possible pending buffers and messages from all the commands (not just the command that you disabled or removed) that are stored to be received by the user-mode from the kernel-mode and when you press 'g', you no longer see any results from previous commands; however, some commands might continue generating new messages, and those new messages won't be removed.
autounpause : if you turn autounpause on, then if you press CTRL+C or run the 'pause' command to break to the debugger, every new event will automatically turn off your break, and you'll start receiving events and messages from the kernel-mode buffers. However, if you turn it off, then you won't receive kernel buffers and messages when you invoke a new event as the debugger will remain in the paused state (for example, paused because of 'pause' command or CTRL+C), in this case, you can resume receiving messages from the kernel-mode buffer by running 'g' command.
addressconverison : if you turn addressconversion on, then in the case of disassembling memory, it converts addresses to object names (if the symbol is available for that address). Otherwise, it shows the address in hex format. This option also affects showing function names in stepping through the instructions.
Examples

Remarks
autounpause and autoflush do not change anything in debugger mode. It is because the buffers are not accumulated and passed instantly in this mode; thus, there is nothing to flush.
