# Barres d'outils et fenêtres ## Overview Windows, toolbars and panels within MuseScore can be repositioned, and you can choose which elements you want to see displayed in them. The default appearance of MuseScore is shown below:

The Status Bar ## Toolbars ### Showing and hiding toolbars To show or hide the [playback](https://handbook.musescore.org/fr/sound-and-playback/playback-controls) controls, [note input](https://handbook.musescore.org/fr/basics/entering-notes-and-rests) toolbar, or the **status bar**: * Select **View→Toolbars...** and check/uncheck the applicable element. ### Rearranging toolbars Pour changer la position des barres d'outils **saisie de notes** ou **lecture**, cliquez et maintenez les six points à gauche de celles-ci puis glissez-les à l'endroit souhaité. Elles *peuvent* être laissées flottantes mais celle de **saisie de notes** peut aussi être glissée à gauche ou en bas de la fenêtre principale — un rectangle bleu apparaît pour indiquer où celle-ci peut être lâchée pour la **refixer**. La barre de **lecture** ne peut être refixée qu'à son emplacement *default*. ### Customizing contents of toolbars To select the icons that you want on view in the **note input** or **playback** toolbars, click on the gear icon to the right of the toolbar:
Gear icon
In the case of the **note input** toolbar, this reveals a dropdown list from which you can hide or display the various icons by clicking on the eye symbol to the left of each one (closed=hidden, open=displayed). In the case of the **playback toolbar**, uncheck or check the various options in the gear menu to hide or display the corresponding elements. ## Windows and Panels ### Docking and undocking panels To undock and move one of the **side panels** (Palette, Instruments, Properties, or Selection filter), click on the three dots on the tab, select the **Undock** option, then drag the undocked panel to the desired position. You *can* leave the panel free-standing but there are also dock positions at the top and right hand edges of the document window—a blue rectangle appears to show that you can drop the panel to redock it at that location. In a similar way, you can redock the free panel back to the sidebar: * To display half-length at the top of the sidebar, drag and drop the free panel to the top left of the sidebar. * To display half-length at the bottom of the sidebar, drag and drop the free panel to the bottom left of the sidebar. * To display full-length in the sidebar, drag and drop the free panel to the center left of the side. You can also redock the free panel in its original position by clicking on the three dots on the tab, and selecting **Dock**. Panels such as the [Mixer](https://handbook.musescore.org/fr/sound-and-playback/mixer) or virtual [Piano](https://handbook.musescore.org/fr/basics/entering-notes-and-rests#selecting-pitch-using-the-virtual-piano-keyboard) can be undocked if desired, by dragging them into position or clicking on the three dots icon and selecting **Undock**. To redock, click on the three dots icon and select **Dock**. The undocked **mixer** can be resized by dragging the edges inwards or outwards. ### Customizing contents of panels To choose which elements to display within the [mixer](https://handbook.musescore.org/fr/sound-and-playback/mixer) or the virtual [Piano](https://handbook.musescore.org/fr/basics/entering-notes-and-rests#selecting-pitch-using-the-virtual-piano-keyboard), click on the three dots, select **View** and uncheck or check the applicable options.
