Enhance Integrated Help System to Display Custom Keybindings with Descriptions

[ckagerer]

Is your feature request related to a problem? Please describe.

I often use custom keybindings within the application, and sometimes I overwrite the default ones. This creates confusion because the integrated help system, accessed by pressing the "?" key, does not display my custom keybindings

Describe the solution you'd like

I would like the integrated help system to display custom keybindings alongside or instead of the default ones. To achieve this, it might be necessary to extend the configuration settings to include a field like "description" for each keybinding. This would allow users to provide a brief explanation of their custom keybindings, which can then be displayed in the help menu

Describe alternatives you've considered

One alternative would be to manually document my keybindings outside the application, but this is not ideal as it lacks the convenience and accessibility of the integrated help system.
