The Main Menu screen element does not support replacing its Ent key with Right for opening or entering menu items. Treat this as a fixed navigation constraint, not a configurable key-mapping fault.
Confirmed Main Menu Key Behavior

Enter a Main Menu item with Ent

Use the existing behavior. |
Replace Ent with Right

Not supported by the Main Menu screen element. |
| Use arrow keys on a historical graph | Select the history context-menu movement mode; the arrow keys then move within the graph. |
Why Arrow Navigation Disappears on Historical Graphs
When movement mode is selected from the history context menu, Right, Left, Up, and Down control movement within the graph. Those keys are therefore unavailable for switching among application screens while that graph interaction is active.
Supported Navigation Design Paths
- Place the historical graphs in the Main Menu and retain
Entas the menu-entry key. - If custom screen switching is required, map a key combination to a UI variable and use application logic to select the target graph.
- An Enum input can also select a graph through FBD logic, but it adds a visible selection element and does not create native carousel behavior.
The evidence does not identify a built-in carousel control or a supported method for assigning Right and Left exclusively to informational-screen rotation while keeping all settings in the Main Menu. Implement that layout only through custom UI-variable logic, subject to the arrow keys already being consumed by graph movement.
Verification
Confirm that Ent opens the selected Main Menu item. On a historical graph, activate movement mode and verify that all four arrow keys move within the graph. If custom UI-variable navigation is used, test it both outside and inside graph movement mode to identify key conflicts.
FAQ
Can I replace Ent with Right in the Main Menu?
No. The Main Menu screen element does not support replacing Ent with Right for entering menu items.
Why do the arrow keys stop switching screens on a historical graph?
In history movement mode, Right, Left, Up, and Down are assigned to movement within the graph.
How can I navigate among four historical graphs?
Place the graphs in the Main Menu, or use a key combination and UI variable to drive custom screen selection. An Enum input with FBD logic is another supported design path described by the evidence.
