During the hot keys are enabled, there are special key combinations with which you can access the data without the password manager in the foreground must be located.
Following scenario: you are surfing on a website known to them and have to log in again. The password manager is open in the background (or in the task tray) and she can now reach with hotkeys.
Depending on which entry is selected in the Password Manager, you can access the appropriate data. Let's say you selected a data item to which a user name, password and a URL is assigned.
In order now to get the username in the field of your browser, select simply the field in the browser and press ALT +1 (the number as a key should not come from the number field). For ALT +2 they get the password in the field, ALT +3 is the URL, etc. If you now have 10 or more fields, you can also start with ALT +0 and then enter 2 more digits with ALT.
The data entries (in the list on the left) can also be triggered when an application has been assigned to them, which is located just in the foreground. Using ALT + arrow keys up and down, you can now navigate through records to which the same application has been assigned.
As some applications (especially Windows applications) use the modifier keys CTRL and ALT separately in order for example by pressing the Alt key to choose the most above menu, you can select the application in hotkey lock are assigned. This ALT and CTRL are not received by this application, as long as they are in the foreground. This behavior can be disabled but whenever you turn off the hotkey (for example, in turn, by hotkey).
The "hidden menu" can be transferred in any application forms and in all its data without having to know them. This allows even long passwords without copy + paste or typing via keyboard shortcut transferred.
What was not mentioned is the importance of the CTRL key. This is explained briefly. It has, in principle, together with the number (ALT +1, ALT +2, ...) have the same meaning as ALT, except that the Enter key is hereby sent.
So you have a form with username and password where the username is already in the field (as used in the browser like), then simply select the password field and press CTRL +2 for the password and sending off the form at the same time.
One more small note: There would be sending the data while holding the ALT key and CRTL unexpected happen, the data is transferred only after the modifier keys (ALT, CRTL) were released.
