Keyboard navigation not fully supported

[Tecnosoft-dev]

Exemple :
In pc version : jumping between messages and select one, there's just scrolling by mouse, its hard to exactly select a specified message.
-when a message is selected the Right-click-menu button found in keyboard should show options related to this message, not texting options.

• also: when exporting chat: the file name in a sent message should be shown and exported, even if i chosen not to export "files".
