-# Interface Understanding
-
-As a beginner, you're only required to swiftly comprehend a few crucial sections
-of the page. The exploration that follows will gradually unveil additional
-functionalities. Bear in mind that interfaces may vary across different
-versions.

-## Text Editor
-
-The text editing zone allows you the liberty to input any desired text or
-establish a new tab through the "New" choice in the file menu at the top. Moving
-or closing tabs can be done with ease as per your needs.
-
-Numerous operations can be performed on your text using options available in the
-Operations Bar. Alternatively, you may utilize standard shortcuts like
-Ctrl+C/V/S for copy, paste, and save operations, or even searching within the
-text.
-
-The edited text within the text box is encoded in UTF8 without any formatting.
-This plain text format ensures that no message alteration leads to confusion.
-While we have plans to introduce rich text editing in the future, the specifics
-are still being deliberated.
-
-### Large Text File Support
-
-GpgFrontend accommodates opening larger files without hindrance. However, when
-dealing with relatively large files, editing of the tab won't be feasible until
-the entire file is loaded. During this time, despite not being able to edit the
-file, you still have the capability to view it.
-
-## Information Board
-
-GpgFrontend presents the outcome of the current tab page operation on the
-Information Board, signifying the success or failure of the operation.
-Additionally, the Information Board's text includes supplementary details to
-assist in understanding the particulars of your encryption, decryption,
-signature, and other operations. Depending on your language settings, the output
-displayed on the dashboard may differ.
-
-The Information Board was conceived to provide a comprehensive view of more
-information within the same space. However, GpgFrontend plans to incorporate a
-graphical interface in the future to augment the user's comprehension of this
-information.
-
-### Color Coding
-
-- **Green**: Indicates a successful operation that has been thoroughly verified
-  and found devoid of any issues. The appearance of green font color signifies
-  an all-clear.
-- **Yellow**: Denotes a successful operation with some potential issues detected
-  during result testing. The yellow font color serves as a subtle alert for the
-  user, necessitating a detailed review of the operation.
-- **Red**: Symbolizes an unsuccessful operation or a significant discrepancy in
-  the operation's outcome. The red font color acts as a clear warning, demanding
-  the user to meticulously inspect the operation's specifics to ensure security.
-
-### Customizable Font Size
-
-Should you find the font size on the information board to be diminutive, you can
-easily adjust it under the 'Application' section in the settings. The default
-font size is 10, and it can be modified to any value ranging from 9 to 18.
-
-### Dashboard Actions Menu
-
-The dashboard actions menu facilitates quick and easy access to common
-functionalities related to the content of the information board. It empowers
-users to efficiently manage and process large chunks of content on the
-Information Board for various purposes.
-
-#### Copy
-
-This function allows users to swiftly capture significant portions of content
-from the Information Board for other applications.
-
-#### Save File
-
-This operation archives the contents of the information board into the file
-system, utilizing the UTF-8 format. Although the resultant output file lacks a
-suffix, it is essentially in a plain text format.
-
-#### Clear
-
-This command promptly purges all content from the information board. The
-clearance includes both the contents and statuses of the information board. A
-new operation (such as encryption) will automatically trigger this clearing
-process.
-
-### Optional Actions Menu
-
-In addition to the Information Board, an Optional Actions Menu will be presented
-below it. If any auxiliary operations can be performed post your main operation
-(such as displaying more detailed information, sending encrypted text via email,
-etc.), the access points for these supplementary tasks will be made available
-here.
-
-## Key ToolBox
-
-This feature presents a comprehensive list of key pairs stored on your device,
-intended for use with Gpg operations. The keys within the ToolBox are classified
-into multiple categories, each corresponding to a unique usage context.
-Additionally, the ToolBox provides access to a variety of common operations, all
-of which can be found in the Key List Menu.
-
-### Usage
-
-Most Gpg-related operations require specifying a key pair (for tasks like
-encryption, decryption, signature, etc.). You can select the checkbox in the
-first column of the Key ToolBox's table to designate one or more keys for your
-operation. Categories that contain only public keys are frequently utilized in
-cryptographic scenarios.
-
-### Classification
-
-The ToolBox showcases categories via tabbed display. None of these categories
-include any expired or revoked keys. To view such keys, you should refer to the
-Key Manager. The default category comprises all private and public keys. During
-any operation, only the keys from the currently selected category will be
-considered for input.
-
-### Columns
-
-Understanding this list is crucial. Let's walk through its components step by
-step.
-
-- **Select**: Check the box in this column to notify Gpg Frontend that you wish
-  to use the key from this row for your subsequent operation.
-
-- **Type**: This column informs you about the key type and whether the primary
-  key exists in your key pair.
-
-  - `pub` signifies that it is a public key, which can be used for encryption or
-    verification operations.
-  - `pub/sec` indicates that the key pair contains both public and private keys.
-    It can be employed for nearly all operations (consult the 'Usage' column to
-    confirm this).
-  - `pub/sec#` shows that the key pair has a public key and a private key, but
-    the primary key is absent from the key pair. This suggests you won't be able
-    to perform certain specific operations (like adding subkeys, signing other
-    key pairs, etc.)
-  - `pub/sec^` implies that one or more keys (subkeys or master keys) from the
-    key pair are in the smart card.
-  - `pub/sec#^` denotes a simultaneous occurrence of the previous two
-    situations.
-
-- **Name**: Represents the identity information of the key pair.
-- **Email Address**: Also denotes the identity information of the key pair.
-- **Usage**: Determines which operations the key pair can execute. Composed of
-  four uppercase letters, each letter signifies a specific use.
-
-  - `C` stands for Certificate. Key pairs containing the primary key generally
-    have this usage.
-  - `E` stands for Encrypt. The key pair can be used for encryption operations.
-  - `S` stands for Sign. The key pair can be used for signing operations.
-  - `A` stands for Authenticate. The key pair can be used to perform operations
-    like SSH authentication.
-
-- **Validity**: A Gpg concept that roughly represents the level of trust in this
-  key.
-
-## Operations Bar
-
-Here, you can execute corresponding operations by clicking on the buttons
-provided. For instance, after inputting text into a text editor and specifying
-the desired key in the key toolbox, you can click the encryption button to
-perform the operation.
-
-Some operations require key specification, while others do not, as will be
-detailed in the respective sections of this document.
-
-### Customization
-
-For operations that you may not use for a while, you have the option to uncheck
-the associated function group in the top menu view. Conversely, for the
-operations you frequently use, you have the ability to add them here.
