 For example, `"take file [blue] air"` selects the file including the token containing letter 'a' with a blue hat.
 
+##### `"head"` and `"tail"`
+
+The modifiers `"head"` and `"tail"` can be used to expand a target through the beginning or end of the line, respectively.
+
+- `"take head"`: select from the cursor the start of the line
+- `"take tail"`: select from the cursor to the end of the line
+- `"take head air"`: selects the mark through to start of the line
+- `"take tail air"`: selects the mark through to the end of the line
+
+When followed by a modifier, they will expand their input to the start or end of the given modifier range. For example:
+
+- `"take head funk"`: select from the cursor the start of the containing function
+- `"chuck tail class air"`: Delete from the token with a hat over the letter `a` through the end of its containing class
+
 ##### `"token"`
 
 The `"token"` modifier expands its input to the nearest containing token. This modifier is often used without a mark, either to select the token adjacent to your cursor or to expand your selection to the nearest containing token range. For example:

 `take blue air past green bat`

+##### Vertical ranges
+
+The `"slice"` range modifier is used to refer to multiple targets that are vertically aligned. It is commonly used with the `"pre"` action to add multiple cursors to the editor. Each cursor is inserted at the same column on each row requested within the command.
+
+- `"pre <TARGET 1> slice past <TARGET 2>"`: Add cursors from the first target through to the second target's line(inclusive end)
+- `"pre <TARGET 1> slice <TARGET 2>"`: Shortened version of above `"slice past"` command
+- `"pre <TARGET 1> slice until <TARGET 2>"`: Add cursors until the second target's line(non-inclusive end)
+- `"pre <TARGET 1> slice between <TARGET 2>"`: Add cursors between first and second target's lines(non-inclusive start and end)
+
+For example:
+
+- `"pre air slice bat"`: Places cursors at the same position on every line (inclusive) between token with hat over the `a` and token with the hat over the `b`. The position will be the start of the token with a hat over the `a`
+- `"chuck tail air slice end of block"`: Delete the end of every line from air through the end of its non-empty line block.
+
 #### List targets
 
 In addition to range targets, cursorless supports list targets, which allow you to refer to multiple targets at the same time. When combined with the `"take"` action, this will result in multiple cursors, for other actions, such as `"chuck"` the action will be applied to all the different targets at once.

+These commands accept multiple selections, and change their order. For example:
