+# Single Key Presses in Interactive Mode
+
+When staging changes in interactive mode (`git add -p`), you have a number
+of options associated with single keys. `y` is *yes*, `n` is *no*, `a` is
+*this and all remaining*, and so on.
+
+By default, you have to press *enter* after making your selection. However,
+it can be configured for single key presses. Add the following to your git
+configuration file to enable single key presses for interactive mode:
+
+```
+[interactive]
+    singlekey = true
+```
