Issue

When using non-English client it's difficult to find which keyword should be used for a particular dungeon or raid.

Suggestion

Add in-game hints with keywords. For example, in "Mythic Dungeons" tab or in "Adventure Guide".

Not sure if I would look in the adventure guide, but the Mythic tab is a good idea.
Keywords are shown without long dungeon name in the info button tooltip, did you notice them there?

Yes, I've seen them in the tooltip.

I see two reasons why additional hints can be useful:

• The more dungeons are added to the game, the more likely conflicts will appear. Some logic should be applied to create a keyword, and this logic can be not obvious to all users.
• Translations are not precise. For example, in Russian client "Shadowmoon Burial Grounds" is roughly translated as "Shadowmoon Necropolis", so can be discrepancies if you try to guess the dungeon's name in English.

Now shows dungeon checkboxes, so I assume this issue can be resolved.
