## Display Format of Function-Key Lines

Command | Function
--- | ---
`%YN` | Displays the function-key lines in normal tabular format.
`%YS` | Displays the function-key lines in sequential format, and only showing those keys to which names have been assigned (`PF1=value`,`PF2=value`, etc.).
`%YP` | Displays the function-key lines in PC-like sequential format; corresponds to `%YS`, except that `Fn=` instead of `PFn=` is displayed before the names.

## Single- and Double-Line Display

Command | Function
--- | ---
`%YA` | All-line display. Displays both function-key lines.
`%YH` | Half display. Displays only one function-key line; for normal tabular display mode (`%YN`), this is the line with the function-key names; for the other two display modes (`%YS` and `%YP`), this is the upper line to be displayed.

## Positioning of Function-Key Lines

Command | Function
--- | ---
`%YB` | Displays the function-key lines at the bottom of the screen.
`%YT` | Displays the function-key lines at the top of the screen.
`%Ynn` | Displays the function-key lines on line `nn` on the screen.
`%Y-nn` | Displays the function-key lines on the `nn`th line from the bottom of the screen. If the line number `nn` or -`nn` is not within the current screen, the function-key lines will not be displayed.

## Range of Displayed Function Keys

Command | Function
--- | ---
`%YF` | Displays the first range of function keys (that is, usually 1 to 12).
`%YL` | Displays the last range of function keys (that is, usually 13 to 24).
`%YX` | Is used to toggle-switch between the two displays.

## Intensified or Reverse Video Display of Function-Key Lines

Command | Function
--- | ---
`%YI` | Displays the function-key lines intensified. Enter `%YI` again to switch back from intensified to non-intensified display.
`%YV` | Displays the function-key lines in reverse video. Enter `%YV` again to switch back from reverse video display to normal display.

## Coloring of Function-Key Lines

Command | Function
--- | ---
`%Y=color-code(s)` | Displays the function-key lines in the specified colors. The color-codes you can specify are the same as with the session parameter `CD`). You can specify up to three color-codes: the first color-code refers to the first function-key line (the one displaying the function-key numbers), the second color-code refers to the second function-key line (the one displaying the function-key names), and the third color-code refers to the background of both lines. For example, `%Y=GRPIYE` would cause the characters in the first line to be displayed in green, the characters in the second line in pink, and the background of both lines in yellow.
