JIRA highly increases the productivity by taking care of reporting, notifications, etc thereby helping users and teams to focus on task at hand. A good way to increase the productivity is to decrease the number of clicks or steps required to perform certain action. For example, in JIRA, one of the things that I use on a daily basis is searching through JIRA based on the strings that I remember.
We can utilize browser's search engine feature to fast track our searching process in JIRA. If you are using Chrome, go to Settings >> Search Engines >> Manage Search Engines >> Add
In the screenshot, I have set my browser to jump to JIRA search on pressing on 'j' button in the Google Chrome address bar. The keyword/shortcut text can be anything you like.
Similar to above, you can even create shortcuts for directly searching the issues or projects.
