Use labels to categorize issues.
Create labels to help organize issues on your team. You can filter by label when creating views and sifting through search results to help you find the issues you need. Labels can be created on in the workspace, or they can be team-specific, so they can be customized to your team's needs. Labels can also be used to create custom analytics using the Google Sheets integration.
L to apply label
L then start typing new label name to create and apply label
Shift L to remove label
O then L to jump into a label page
F to filter by label
Apply labels to any issue with the shortcut L. Go to either the workspace label settings or team settings to create, edit, or delete labels and to view a list of all labels and how many issues are categorized under them.
Go to Workspace labels or Team settings > Labels to create new labels. You can also create labels in the Add label flow. Take the action to apply a label, then type the name of the label you want to create, and it'll automatically be saved to your team's labels.
Go to Workspace labels or Team settings > Labels and then hover over the label name to bring up the option to edit or delete labels. Deleting labels is not reversible. If a label is in use, you'll still be able to delete the label and doing so will remove it from any issues.
While creating or editing a label, select the colored dot to bring up a color picker. Select the # option to specify a hex code.
Labels created on the workspace can be used by all teams. You should create labels that are used by all teams (e.g. "Bug") in the Workspace labels instead of the team-specific label settings.
Even team-specific labels "act" like global labels when filtering All teams or multi-team views.
As long as labels in different teams share the same letters (e.g. bug and Bug, no need to match capitalization), filtered results will show all issues across all teams that match the label. This affects custom Views, My Issues, Project All team views, and general search (/). Unfortunately, it does not extend to the API (you'll have to use the unique identifier for each team's label).
If you only want to see results for a specific team's labels in a multi-team view, add a team filter on top of the label filter.
