Help? Troubleshooting for Users

Steps for Zoom

  1. "Join Audio" for conversation
  2. "Share" an individual application or desktop
  3. Sharing the application is less confusing (Chrome, Safari, Firefox, etc.)  
  4. Use the chat in Zoom if needed

Notes on sharing your screen

  • This will allow you (or the other user) to share the entire screen or just individual windows.
  • While sharing, both users will find on-screen annotation tools, which allow you to highlight and mark up the screen (sort of like a SMART Board!).
  • During screen sharing, whether it's your screen or the other user's, you can request or give up keyboard & mouse control. For example, if you are sharing your own screen, this would allow the other user to interact with it.

Sharing Options

Best Practice: Choose to share your browser



View of the Annotation Toolbar

Once you've started a screensharing session, select “Annotate” from the sharing menu to begin annotating on your shared screen. This will open the annotation toolbar. Click on a tool to select it.

This will open the annotation toolbar. Click on a tool to select it.

  • Mouse: Use this to switch back to your regular mouse cursor.
  • Select: Use this to drag and drop objects you've added (e.g. text) around the screen.
  • Text: Add text to clarify specific portions of the screen.
  • Draw: Use freehand drawing to literally draw attention to a particular spot on screen.
  • Spotlight/Arrow: Turn your cursor into a spotlight or arrow to help capture the user's attention, so they look where you're pointing.
  • Eraser: Erase some or all of your prior annotations.
  • Format: Use this to select the formatting of the other tools (e.g. the color of text and lines).
  • Color: Add a highlight splash of color to denote a particular portion of the screen.
  • Undo/Redo: Step backward and forward in time to undo/redo previous changes.
  • Clear: Removes all previous annotations with one click
  • Save: This downloads a screenshot that includes your annotations. These will be saved to your computer's local recording location.

For tools like Text, click on the screen where you want to apply it. For tools like Draw and Eraser, click and drag on the screen -- just like if you were drawing or writing.

When finished marking up the screen, you have a few options:

  • If you would like to save your annotations, click on the Save button. This will capture the current screen and all annotations as a screenshot saved to your local device. Once saved, you can share the screenshot with your patrons via the chat box.
  • To clear all annotations from the screen, click on the Clear button.
  • To leave the annotations on screen but continue with the session, click on the Mouse button to return to your normal cursor.

Sample of Annotation

​If you would like to turn on your computer's webcam in addition to joining the meeting audio, you totally can! However, this is entirely optional.

There are different layout options for displaying webcam video while simultaneously sharing your screen.

*Webcam Video

  • Never feel obligated to use the camera
  • Be careful, use good judgment
  • No one wants to see anything inappropriate
  • Consider only using the camera for meetings, consultations, & with individuals that you know

Using the built-in chat box (optional)

You may find it helpful to use the in-meeting chat feature during a screensharing session so you don't have to switch back and forth with LibChat.

*Please note, however, that your chat transcript is not saved within your LibChat chat transcript. Instead, you would need to manually save your in-meeting chat transcript separately before exiting the screensharing session.

Ending a screensharing session

When you've finished sharing your screen, you have a couple of options:

  • To continue the meeting, but stop sharing your screen (so you can continue talking over meeting audio), click the Stop Share button in the screensharing controls.
  • The options to stop sharing or end the meeting in the screensharing controls

To completely end the meeting

  • Click on the End Meeting option.
  • If you are sharing your screen, you'll find this under the More... menu in your screensharing controls.
  • If screensharing has been stopped, then you'll see a red End Meeting button at the bottom of the meeting window.
  • Closing the meeting window itself.

*Please note that this will only end your screensharing session -- your LibChat session will remain active until someone ends the chat.

Some Tips & Tricks
  • Before sharing your screen open up a new browser window to share
  • Minimize and position windows to view:
    • Chat (libanswers)
    • Zoom meeting
    • Browser that is being shared (will have green border)
  • Set up your preferences
  • Explore your toolbar: learn how to close meetings, record, etc.
  • You can only have ONE zoom meeting at a time. You can not be in a zoom meeting & open a screenshare.

Test your Audio


There are two ways to join meeting audio, joining via computer or joining via telephone. Follow these sections to test your audio before or after joining a meeting.

You can also join a test meeting if you want to test your audio and familiarize yourself with meeting controls.


  • Microphone, such as the built in microphone, a USB microphone or an inline microphone on headphones
  • Speaker or headphones

Testing Audio Before Joining a Meeting

If you haven't enabled the setting to automatically join by computer audio, you can test your speaker and microphone before joining a meeting:

  1. Use one of the methods to join a meeting.
  2. Click Test speaker and microphone.
  3. The meeting will display a pop-up window to test your speakers. If you don't hear the ringtone, use the drop-down menu or click No to switch speakers until you hear the ringtone. Click Yes to continue to the microphone test.
  4. If you don't hear an audio replay, use the drop-down menu or click No to switch microphones until you hear the reply. Click Yes when you hear the replay.
  5. Click Join Computer Audio.
  6. Click Join with Computer Audio to join the test meeting with the selected microphone and speakers.

Microphone Troubleshooting

  • If you are on on Mac OS 10.14 Mojave or earlier and can't access the microphone, check your operating system permissions to confirm that Zoom has access to the microphone. See Using the Zoom Client and Zoom Rooms with Mac OS 10.14 Mojave for more information.
  • If you are on Windows 10 and can't access the microphone, use the Windows search box to navigate to Microphone privacy settings. Switch on the Allow apps to access your microphone toggle, and enable access for Zoom.
