Auto-Type, Global Auto-Type Hot Key and Drag&Drop
KeePass can minimize itself and type the information of the currently selected entry into dialogs, webforms, etc. Of course, the typing-sequence is 100% user-customizable, read the documentation file for more.
KeePass features a global auto-type hot key. When KeePass is running in the background (with opened database) and you press the hot key, it looks up the correct entry and executes its auto-type sequence.
All fields, title, username, password, URL and notes can be drag&dropped into other windows.
