I am fairly new to Trello.
I am trying to select multiple cards to assign a member to each card or to change the colour of multiple cards.
According to the following link I should use Ctrl+click to select each card but when I use this it opens the card I have clicked in a new tab.
The link also says that I should use the Action button but I only can find the Action button in the card itself.
Andrew clarification would be helpful.
That link is talking about an extension for Trello that, to be fair, I'm not aware of. Those extensions are not developed by us so we don't really know how they work. They are usually not harmful, but I'd advise doing your own research before using them.
There is a Power-Up that allows bulk actions. That is not developed by us, but it's verified by our ecosystem team, so you might want to give that a try: https://trello.com/power-ups/5e4464985fd190825d164de3
