+
+- closes some game interfaces by pressing their hotkeys again:
+  * 'I' key for Inventory
+  * 'S' key for Skilldex
+  * 'Z' key for Pip-Boy
+
+- extends the functionality of the 'Space' key (Caps Lock must be off):
+  * takes all items in the loot screen
+  * makes the offer in the barter screen
+
+- Note:
+  * the uppercase 'A' (shift + A if Caps Lock is off) is the built-in hotkey for the TAKE ALL button on the loot screen
+  * the lowercase 'm' is the built-in hotkey for the OFFER button on the barter screen
+
+
+Requires sfall 3.5 or higher
+
+To use, copy gl_uihotkeys.int to your scripts folder.
+
+This mod is a simple example of how you can use HOOK_KEYPRESS hooks.
