General Settings :
Always use the "TAB" key to validate an entry field and navigate to the next one.
In any message displayed, you can use the "Enter" or "Escape" keys to accept or refuse it
You can hide - unhide the Left navigation Panel (you have more surface visible onscreen) with Ctrl-N OR from this icon in the main frame toolbar 
(the main "Data Management" module (as well as the Projects & Profiles and Styles one) are automatically set to full width for easier use.)
Keyboard shortcuts used are :
Ctrl-D = Data Management
Ctrl-E = Extensions
Ctrl-F = Films & Videos
Ctrl-H = Help
Ctrl-N = Toggle Navigation Bar On/Off
Ctrl-O = ODBC Connections
Ctrl-P = Projects and Profiles
Ctrl-R = Replacement Groups
Ctrl-S = Settings
ALL main windows close using the Escape Key
When a Module (except Projects & Data management) is opened other modules can be opened BUT the "previous" one will be closed by DMC so as not to have multiple screens opened at the same time.
When you are in this "reserved" module (Data Management) you can access from the Menu all help topics or open DMC Folders.
Use the Main frame toolbar buttons to Insert - Edit - Delete records in all the modules 
You have to close some Modules to be able to open others but you can also, for example, open Settings and directly open Profiles .....Settings will be closed automatically

You also have in the main frame two buttons which come alive only when you are in the Data Management module and only when you are in the 'DATA' tab or the 'Transferred Data' one :
Those buttons will let you export to HTML-PDF-DOC-CSV-XLS all the SOURCE data records you are about to work on OR all your MAPPINGS done

You also will have the possibility to eMail or FTP those exported files ....

You have in the main frame toolbar a button which opens up only while you are transferring your Data
![]()
If you click on it a Confirmation Message will popup to let you Cancel or Continue the processing
If you click on 'Yes' the transfer will be canceled ....
When doing an ODBC SQL transfer, this button will only be visible while the sql script is created. While the same sql script is executed you will have another window in the middle of the screen to cancel it also

By clicking on the 'Stop' Button, you will again have a confirmation message popup to let you cancel or not the sql insertion

If you click on 'Yes' the transfer will be canceled ...
Screen resolutions :
The main frame is resizable and this feature will let you adapt the screen to your best preferences.
The initial position will be restored when you request it from the "Settings" module
All the inner screens are 800x600 compatible but can be reduced to smaller sizes.
HyperFile : The version 12.01 - and previous ones - ODBC driver used to implement the support of these tables is VERY unstable (we recommend upgrading to the newer version 14 ODBC driver) : reading a Table can receive error (which are non existent errors in sql language) messages or not.
