Fonts in the FS/2 window may be set by using the standard OS/2 drag and drop method or by using the the font selection tool on the Settings Notebook Fonts page.
Note: The Data Panel dynamically adjusts to the font set in both the X: Used button and subwindow. While each button and subwindow will adjust in both height and width, the major effect is on the length of the Name and Message windows. Since the width of the primary window doesn't change, these two windows adjust to the remaining width.
Drag and Drop
Drag a font from the OS/2 Font Palette to any of the following:
FS/2
window titlebar
PM menu
Toolbar
Drives window
Active Directories or Files window
Any Data Panel pushbutton or subwindow
To set a different font in the Drives window, set the active Files window font first. Then drop a font on the Drives window. Otherwise the font set in the active window is also set in the Drives window.
It is not possible to set a different font for the Directories and Files window.
To set the font for all pushbuttons in one drop, drop on the X: Used button in the Data Panel.
To set the font for all subwindows in the Data Panel in one drop, drop on the X: Used subwindows.
Font Selection Tool

Settings Notebook - Page 4_1
The Fonts page provides a method for customizing fonts in the FS/2 main window by selected targets. You must first select where the font is to be applied using the Windows, Data Panel, Menus or Dialogs radio buttons. Then select the font and font size. Finally, push either the Apply or Save button.
When a font is applied to the menus, it is applied to the PM menu and all context popup menus.
The Save pushbutton sets and saves the font selection for subsequent FS/2 sessions.
The Apply pushbutton sets the font for trial. The font is saved when the notebook is closed. Pushing Reset before closing the notebook should restore the previous font.
