If you are using IDA for the very first time, here are some commands that you will find very useful:
- convert to instruction : the hotkey is "C" - convert to data : the hotkey is "D"All the changes that you made are saved to disk. When you run IDA again, all the information on the file being disassembled is read from the disk, so that you can resume your work.
For other commands please refer to the menu system and the help.
