+* `tabmove '[-+]?n'`: Moves the active tab to another slot. `n` is an integer.
+ If `n` is prefixed with `-` or `+`, then it represents a relative position
+ (e.g. `tabmove +2` moves the tab to the right by `2`). If `n` has no prefix,
+ it represents an absolute position (e.g. `tabmove 2` moves the tab to slot `2`).
