This allows you to combine many different icon into one, central spot instead of many different places.

To lock and unlock Tell Me When, type "/tmw" or "/tellmewhen".

When you first log in with Tell Me When installed, you will see one group of four icons in the upper left hand corner of your screen.

On the icon editor, you will notice three tabs: Main, Conditions, and Group settings. Once you have selected a condition type, there are several settings that can possibly be configured for it (although not all condition types have every setting configurable): Aside from the regular icon types that Tell Me When has (cooldown, buff/debuff, etc), there is also the meta icon.

The meta icon is a unique icon type in that it is not configured like any of the other icon types.

For example, the Death Knight ability Icy Touch applies a Do T called Frost Fever.

If you selected a buff/debuff icon, you will also need to enter the unit(s) that you wish to check for the buff/debuff.The icon will have the correct texture after you encounter the buff/debuff while playing.Remember that buffs and debuffs sometimes have different names than the items, abilities, and talents that provide them.Also note that totem icons, cast icons, and weapon enchant icons can have this editbox left blank in order to have them track any totem/cast/weapon enchant.For buffs and debuffs not in your spellbook that were not entered as Spell IDs, Tell Me When will at first show a pocketwatch icon to indicate that it is waiting to learn the texture for the buff/debuff.The fake hidden option allows meta icons to check an icon without it actually ever showing, causing it to only appear on the meta icon, and not in its original spot.
