What key combination allows you to enable all waveforms at once?

The ability to enable all waveforms at once by using a specific key combination is essential for efficient audio editing in Media Composer. The correct key combination, which is ALT + click on the waveform, allows you to quickly activate or view the waveform information for all audio tracks in your timeline. This is particularly helpful when you need to assess or adjust levels across multiple audio tracks simultaneously.

Using the ALT key enhances this interaction by allowing the command to apply universally to all selected items without the need to individually select each waveform, thereby streamlining your workflow. This feature is especially useful in complex projects with numerous tracks where monitoring audio levels visually can save time and improve the accuracy of your edits.

In contrast, other combinations such as CTRL + click, SHIFT + click, and double-click do not enable this collective viewing or action for waveforms. They may serve different functions, such as selecting multiple items or performing other commands, but will not provide the same result as the ALT + click combination. Understanding these shortcuts can greatly enhance productivity and efficiency when working in Media Composer.
