Add Events to Google Calendar Via SMS.\n\nIf you're at the airport and forgot to schedule a meeting in your Google Calendar, don't worry: You can easily add events via your cell phone in a few quick steps. \n\nFirst, sign into your Google Calendar account and choose "Settings." Then, click the "Mobile Setup" tab and enter the necessary information. A verification code will be sent to your phone; enter the code in the appropriate field and click "Finish setup."Once the setup is complete, you can send events to your calendar via your phone. Do so by texting the details of your event (for example: "Dinner with John at Jimmy's 6:30pm May 16) to GVENT (48368). You'll receive a confirmation text message shortly after, and the event will appear in your calendar. 3. Whiteboard Collaboratively With Google Drawings.Google Drawings is the newest app added to Google's suite of cloud-based tools. This stand-alone editor in Google Docs lets you create charts, diagrams, designs and other schematics\u2014perfect if you're working on visualizing a project timeline or even mind-mapping an idea.To access Google Drawings, sign into your account and click "Documents." Then click "Create new" and choose "Drawing" from the drop-down menu to begin your work. A few other highlights: You can edit your drawings in real time with anyone you choose by selecting "Share" and inviting people. You can also chat with others who are editing your drawing, from within the drawings editor. These two features will be rolled out fully by next month; right now you can opt in to its "preview" by visiting your Docs settings page, choosing the "Editing tab" and clicking "Create new text documents using the latest version of the document editor." Also, the drawings editor supports alignment guides, snap to grid and publishing drawings as images. 4. Turn PDFs into Editable Text.\n\nIf you've downloaded a PDF that you want to edit, or if you've scanned in a document that you want to convert to a Google Doc, use the Google Documents List API\u2014a tool that uses optical character recognition to convert high-resolution image files with text into text that you can edit.\n\nTo do this, log into your Google account and visit this site. Select the file you want to convert from your computer and click "Start OCR import." Note that your file has to be fairly high resolution\u201410 pixel character height is recommended. The maximum file size is 10 MB. When your upload is complete, the document will load in Google Docs, where you can make changes to it. Depending on the quality of the document, some words may not translate. These will be highlighted in yellow and say "unrecognized text."5. View Your Calendar Events in MultipleTime Zones\n\nIf you travel frequently or hold offices in multiple time zones, you can configure your Google Calendar to preview according to more than one time zone, eliminating confusion and frantic time calculations before meetings.\n\nTo enable this, visit the "Settings" tab in your Google Calendar. Under "Your current time zone" choose to add an additional one, and label it appropriately. When you visit another time zone, visit this page again and click the "Swap" button on the right. This will configure your calendar so that all meetings and appointments will appear in your current time zone's time. \nStaff Writer Kristin Burnham covers consumer Web and social technologies for CIO.com.
