Use Short Codes to assign Contacts/Projects/Tasks to Time Entries
Short Codes are an easy way to refer to Contacts, Projects, and Tasks in the log bar drop-down. Think of them like a Twitter Username — you can set a Short Code to anything you'd like, just make it memorable.
To bring up the picker in the log bar:
Type @ (SHIFT + 2) to pick a Contact
Type # (SHIFT + 3) to pick a Project or Task
Note: On the mobile app, the # key opens the Project picker only. Tap the Tag button to pick a Task.
To change a contact's short code, click the Contacts screen, search for the contact you'd like to change, and click "edit".
To change a task's short code, click the Tasks screen, search for the task you'd like to change, and click "edit".
