Finding the task/card you need could be accomplished in 3 ways.
1. You can open a project and press the letter J on your keyboard to "jump to task". This will open a modal and you can start typing and press enter when you find the item you are looking for.
2. You can filter project tasks. In the right sidebar, there is an input that you can use to filter tasks by name, task ID, assignee, task type, status, milestone and label. If you know the item name, you can just start typing it and it will be the only item left. However, It might be on a different list so pay attention to your lists when in list view mode.
3. You can use Quick Search or Global Search and find any task even if you are outside the project. For more information about the Quick Search please go to https://help.ora.pm/article/82-global-search
