  @subsection Decrypt/Verify Data from the Clipboard
+ The most common case is propably that you got a signed email and
+ now you want to verify it. For this procedure, you have to copy
+ the entire signature in the clipboard. The easiest way is to
+ use CTRL+A and CTRL+C, then all available text will be copied.
+ WinPT (GnuPG) is smart enough to figure out the signature related
+ data. Now go to the taskbar, display the popup menu and select
+ Clipboard->Decrypt/Verify. Now a new dialog, the verify dialog,
+ should be available on screen with all information about the
+ signature. For example who is the signer, when was it signed
+ how much do you try this key and what was signed and most
+ important, the status of it (is the signature good or BAD).
+ A special case is when you don't have the public key to verify
+ the signature, if this happens WinPT offers to download the key
+ from the default keyserver. If the key was not found, the procedure
+ is aborted because without the key the sig cannot bed checked.
  @subsection Sign the Clipboard
+ We assume that text that shall be signed is already in the
+ clipboard. If not, select the text you want to sign and copy
+ with via CTRL+C in the clipboard. Now go to the taskbar and
+ open the peopup menu, Clipboard->Sign. If you just have one
+ secret key, the passphrase dialog will be automatically shown.
+ All you need is to enter your passphrase and confirm. In case
+ of more available secret keys, a list with all keys is shown
+ and you can select which key shall be used for signing.
+ The output is always a cleartext signature which is in text
+ format. Do not try to sign binary clipboard data, the result
+ would be unpredictable and not readable by human beings.
+ @section The Current Window Support
+ Compared to the clipboard mode, the CWS mode has some advantages.
+ Let us assume that you want to extract text from an editor window.
+ With the CWS mode, the program automatically tries to focus the
+ window to select the text and to copy it to the clipboard and
+ execute the selected command (Sign, Encrypt, Decrypt).
+ No manual user interaction is needed. Except this different behaviour,
+ it is very likewise to the clipboard mode and thus we do not describe
+ each command again.

+ @subsection Sign a Public Key
+ If you verified that a key really belongs to its owner, you
+ should sign the key to integrate it into your Web of Trust
+ and also to mark the key as valid in your keyring. Do not sign
+ a key you just got via email with the request to sign it. Anybody
+ can create a key with your (or better ANY) name, these information
+ are no hint to whom the key really belongs. You can check a key
+ by meeting or calling the key owner and verify the key fingerprint
+ of the key with the one published by the key owner. Additional checks
+ should be to watch at his driver license or the identity card to make
+ sure that name of the key matches the name of the key owner. After
+ this procedure is done, you can open the Key Manager, select the
+ right key and either use the context menu "Sign Key" or use the
+ toolbar button.
+ The next dialog will summarize the key information and some
+ additional options. For example if the signature should be
+ local or exportable. Local means the signature will be stripped
+ if you export the key and no one else except you can use it to
+ calculate the validity. If you mark the signature exportable,
+ any other user can see and use it. Now you can select the key
+ you want to use to sign and enter the passphrase. Confirm with "OK"
+ and the key will be signed. Now the validity of the new key is
+ "Full". It is propably a good idea to set the ownertrust of the
+ key. For a detailled description, see the chapter "Key Ownertrust".
+ @subsection Key Ownertrust
+ First we should explain what the ownertrust of a key is. The ownertrust
+ is a measurement how much you trust somebody to certify and check keys
+ of other people. For example, if you know that Bob is really the owner
+ of the key, you should sign it. But he is also known to sign other keys
+ without checking the idenity of the other key owner. Values for the
+ ownertrust are 1) Don't Know 2) Don't Trust 3) Marginal 4) Full
+ and thus you should propably use an ownertrust value like "Marginal".
+ But this is a personal decision and stored in a separate file and
+ never exported with the public keys. For further information, please
+ take a look into the GNU Privacy Handbook.
+ Just a last work on Key Pairs, they are automatically marked as
+ "Ultimate" because the key belongs to you and you trust it implicit.
+ @section The File Manager
+ @subsection Introduction
+ The File Manager is no replacement for an Explorer Extension.
+ If you secure your files frequently and you want to do this
+ fast and easy, I suggest to install GPGee. It is a program
+ which integrates itself into the explorer and provide menu
+ entries in the context menu of files and directory. But the
+ File Manager can be very useful if you just want to decrypt
+ and/or encrypt some files without additional programs. You
+ can find the File Manager via the symbol in the taskbar,
+ right click and then "File Manager".
+ @subsection An Overview of the GUI
+ First there are different ways to add (open) files in the
+ Key Manager. The easiest way is to use drag and drop to
+ add files into the File Manager. Just drag a file from the
+ explorer and drop it into the File Manager window. The second
+ way is to use File->Open. A dialog opens which is common for
+ all "File Open" operations in most Windows application. Now
+ you can select one or more files and confirm. The files will
+ be automatically added to the File Manager window. The main
+ window consists of a listview with three rows.
+ The first row is the status of the file. It can be "ENCRYPTED",
+ "SIGNED", "PUBKEY", "SECKEY", "SIG" or "UNKNOWN". Dependent on
+ the file status, the File Manager offers different choices. For example
+ "SIG" enables the verify options in the (popup) menu. "UNKNOWN" is
+ the default for all plaintext files.
+ The second row is the file name. And the last row is the status of
+ the operation. It can be either "", "SUCCESS" or "FAILED". An empty status
+ means no operation was started yet. FAILED indicates that the
+ GnuPG operation failed. In this case an error message was issued before.
+ Now it follows an example:
+ We assume that user wants to encrypt "c:\My Ideas\GPG GUI.txt".
+ Drag the file from the Explorer and drop it into the open File
+ Manager, the main window. The file will be added and recognized
+ as "UNKNOWN". Now we select the file and right click, a popup
+ menu is shown and we select "Encrypt". An new dialog is opened
+ which looks similar to the Clipboard Encryption dialog. Just
+ select the recipients and confirm. In contrast to clipboard encryption,
+ file encryption offers some more extra options. They are described
+ later. And hour glass will be shown as long as GnuPG takes to encrypt
+ the file. When the procedure is done, the third row should be change
+ to "SUCCESS" and the first row to "ENCRYPTED".
+ @subsection General Options
+ Now we describe the general options which are possible in some
+ File Manager dialogs.
+ @itemize
+ @item Text Output
+ When this option is checked, the output will be encoded in ASCII armor.
+ This can be useful if the file should be transfered via email. The
+ size of the output file is larger than the usual binary output.
+ @item Wipe Original
+ If this option is checked, the original file will be deleted after
+ successfull encryption. This can be useful if data should not be
+ available in plaintext any longer on a machine.
+ @end itemize
