Dark mode is available in PDF-XChange Editor, but it is disabled by default. You can manually enable it, or activate an option to ensure it changes in accordance with your currently selected windows theme (note that this options is for users who switch theme mode with some frequency).

If you want to enable dark mode, then open the preferences with Ctrl+K, move to the "Customize UI" category, then select either "Black" or leave the setting on "Default" and select the "Allow Dark Mode from system" box. Note that manually selecting any option in this list will disable any automatic changes taken from the system theme.

When dark mode has been enabled the UI will update as detailed below:

If there is a function you cannot locate, we now offer a Quick Launch function, located by default in the top right area of the Editor:

Simply search for any command that you are trying to locate, and you can make quick use of it by clicking on the tool from this menu.

If you would like to add one of these tools to the toolbar, you can click and drag the tool to pick it up and place it in a location of your choosing:

Clicking the arrow or pin (detailed below) will allow you to Compress, Expand, and Hide the toolbar.

Above is the Default View. Detailed below is the Unpinned View. This mode is ideal for users with minimal screen space as it is possible to click headers in order to open/close ribbon tabs:

Note that the toolbar is thinner in the unpinned view, and you can double-click headers to expand and pin the relevany section of the UI open.

This New UI will resize and remove some of the unnecessary text depending on the width of the editor window.

If you want to reduce the size of tool icons, then right-click a toolbar and click Customize Toolbars, then navigate to the options header and select the "Reduce large icons in toolbars" check box:

Many users found that even the above proved to take up too much space in the Classic UI layout. We have now removed the properties toolbar, and replaced it with the Format tab, which minimizes with the other headers when the toolbar is unpinned.

If you prefer the Classic UI layout, then you can switch back to it at any time by clicking on the UI Options dropdownmenu and selecting Switch to Classic Toolbars:

Note that it is also possible to minimize the icons detailed in the Classic UI, as detailed below:

**Note: many of the menus change slightly with this layout. If you are using the Classic UI and encounter an issue for which you must ask support for help, then please include a note that you are using the Classic UI in the initial email so we can assist you better.

When you are in the Commands section of the customize window detailed above, you can also add or change keyboard shortcuts associated with tools. This is possible in the properties section for the tool, as detailed in the Highlight Text tool below:

You can the specify a new shortcut for the tool - the example above uses Alt+H. Note that you must use the desired action when assigning keys (i.e. pushing the two keys instead of typing a,l,t,+,H). If there is a conflict, then the Editor will provide a warning and the shortcut will not work.
