 Object Selection
 ----------------
 
-Using alt-i and alt-a, you can select some text object, the starting
-point is always the last character of the selection.
+Some keys allow you to select a text object:
+
+ * _alt-a_: selects the whole object
+ * _alt-i_: selects the inner object, that is the object excluding it's surrounder.
+            for example, for a quoted string, this will not select the quote, and
+            for a word this will not select trailing spaces.
+ * _[_: selects to object start
+ * _]_: selects to object end
+
+After this key, you need to enter a second key in order to specify which
+object you want.
 
  * _b_, _(_ or _)_: select the enclosing parenthesis
  * _B_, _{_ or _}_: select the enclosing {} block
  * _[_ or _]_: select the enclosing [] block
  * _<_ or _>_: select the enclosing <> block
- * w: select the whole word
- * W: select the whole WORD
-
-When it makes sense, _alt-i_ selects the inner object and alt-a the whole
-object. For example _alt-i_ will only select the inside of the parenthesis,
-for words, the difference between _alt-i_ and _alt-a_ is that _alt-a_ also
-selects the following blanks.
+ * _"_: select the enclosing double quoted string
+ * _'_: select the enclosing single quoted string
+ * _w_: select the whole word
+ * _W_: select the whole WORD
