The word slot has many meanings, including:
A slot is an elongated depression, groove, notch, or narrow opening, especially one for receiving or admitting something, such as a coin or a letter. It also refers to a position in a group, series, or sequence, such as the slot for a flight on a busy airport’s schedule. The phrase may also be used figuratively, as in She slotted the piece of wood into the groove.
In bots, slots can be mapped to various types. These types determine how the bot processes the information contained in a slot. To add a new slot type, click Add Slot Type on the Slots page or in the left pane of the bot editor. For example, if you want your bot to match only flight numbers, you can map the slot to a Number slot type by using a regular expression (regex).
In aviation, a slot is an authorization for an aircraft to take off or land at an airport during a certain time period. Air traffic control assigns slots to help avoid the large amount of congestion that can occur when many flights attempt to take off or land at the same time.
