How do you access a weekly timesheet to update it during the week?

I've created a weekly timesheet and added some information. Now, two days later, I want to go into it and update for the last two days. However, I can't seem to find any shortcuts to it on the menus. The only way I can access it is to go into the Help screen, search for weekly timesheets, and it gives me a link I can click "Jump to Weekly Timesheets". Surely there must be a shortcut to avoid this??
