Outputs a hint message to the right of the screen (left of the screen in Operation Flashpoint) with a sound (except in Armed Assault).
To split message in multiple lines either use Structured Text or \n (in lower case).
Note
Armed Assault: Armed Assault hints are silent. For later titles, see hintSilent.
Operation Flashpoint v1.00 Armed Assault v1.00 Arma 2 v1.00 Hint messages that exceed the screen may lead to crashes.
Arma 3 v1.00 The game would not crash but suffer FPS drop / temporary freezing.
Be careful when using hints to visualize the effects of commands using the Debug Console. Hint can accept an undefined variable and neither the error nor the hint is shown, the command simply fails. Also notice how the hint command should be hint str _i;:
In a script, an "undefined variable" error will be shown as expected.

Contrary to previous games, Arma 3 will happily display hints that far exceed screen space.
However, as hints get longer, FPS suffers tremendously. tested in Debug Console, A3 1.32.127785 with the following:
Results were: 59.7015 and 5.17297, respectively. Drawing a hint even longer than this, such as nearestObjects with a radius of 10,000 or 100,000 reduces your FPS so much Arma 3 appears to crash, though it doesn't.
Unrelated: Hints will stay on screen for 30 seconds, then fade away over the course of 5 seconds. Tested with: A3 1.32.127785
DreadedEntity
An open dialog will pause the 30-second hint fade timer.

Feint
The hint sound is audible only when you have the music volume turned up above 0 in the audio settings.
Otherwise, it seems to act the same as hintSilent.
This is important because if you are running a hint that fires at 30 fps or more, the hint will slow down machines that have the music volume turned up but won't slow down machines that have the music volume turned off.
Best practice is to use hint for an alert to the player and use hintSilent for a makeshift display of data to the player that is updated fairly often.
