 For the purposes of development, you may want to review the detailed specifications for keys and their codes on the [[OLPC_Keyboard_layouts|Keyboard Layout]] page.
-This section should also go into more detail on the global keyboard shortcut tool which allows children to adjust their preferred key bindings, both at the OS level and for individual activities.  Again, this is an interface that activities should implement, so there should be an API link.
+* ◆ '''CTRL''' (U+25C6) will be the main modifier key. It will be used to define "base" shortcuts. For instance, ◆A will "select all" in a text editor.
+* ◇ '''ALT''' (U+25C7) should be used for optional modifications (or ALTernates) to base shortcuts. For instance, ◆S will perform a standard "keep" and ◇S could be "keep as...". ◆V is paste, ◇V is "paste and remove from clipboard."
+* ⇧ '''SHIFT''' (U+21E7) can work in two ways. Its primary use would be as an inversion modifier, such that it inverts the meaning of the base shortcut. For instance, ◆Z is undo and ⇧◆Z is redo. ◆TAB is next activity, ⇧◆TAB is previous activity. SHIFT can also be used to create a second set of "base" shortcuts which are less often used.
+The FN key is reserved solely for system level operations, and generally for those that map to functions which are printed on the keyboard itself.
