# Edit ### Undo {% hint style="info" %} Keyboard shortcuts: * Windows: Ctrl + Z * macOS: ⌘ + Z * Linux: Super + Z {% endhint %} Undoes the last editing operation you performed to your project. You can undo as many times as you want, all the way back to when you opened the window. To undo many operations, select History from the View Menu. The name of this menu item will change to reflect what will be undone; if you just recorded some audio, the menu item name will be Undo Record. ### Redo Redoes any editing operations that were just undone. After you perform a new editing operation, you can no longer redo the operations that were undone. ### Cut Removes the selected audio data and/or [labels](https://manual.audacityteam.org/man/label_tracks.html) and places these on the Audacity clipboard. Audio or labels after the selection move leftwards. ### Copy Copies the selected audio data to the Audacity clipboard without removing it from the project. ### Paste Pastes audio which has been [cut](https://manual.audacityteam.org/man/edit_menu.html#cut) or [copied](https://manual.audacityteam.org/man/edit_menu.html#copy) to the Audacity clipboard, either inserting it into the [selected](https://manual.audacityteam.org/man/audacity_selection.html) track(s) at the cursor point, or replacing the current selection region(s). ### Delete Similar to Cut, but removes the audio data and/or labels that are currently selected without copying them to the Audacity clipboard. ### Group Clips Allows you to group clips and labels ### Ungroup Clips Ungroup already created groups of clips and labels ### Duplicate If a clip is selected, then creates a new track containing only the current selection as a new clip. If a track is selected, then duplicates the entire track. ### Delete and Close Gap (per track) Deletes the selected region within clip(s) and merges the clips inbetween. ### Clip Menu that allows certain interactions: #### Rename Clip Allows you to rename the clip #### Trim Clip Trims the clip around the created selection #### Split Splits the clips into 2 clips at playhead crossing #### Split into New Track #### Split clips at silences #### Join Selected Clips #### Group Clips #### Ungroup Clips ### Silence Audio ### Audio actions across Labels ### Manage Labels ### Metadata Editor ### Preferences --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
