   • Default cache mode - used to select the cache mode for the font characters. It’s not recommended to switch it without any reason. It can be helpful in some cases only, for example, when an issue in the Google Chrome browser with enabled hardware acceleration occurs.

     The PDF Editor has two cache modes:

     1. In the first cache mode, each letter is cached as a separate picture.
     2. In the second cache mode, a picture of a certain size is selected where letters are placed dynamically, and a mechanism for allocating/removing memory in this picture is also implemented. If there is not enough memory, a second picture is created, etc.

     The Default cache mode setting applies the two above-mentioned cache modes separately for different browsers:

     • When the Default cache mode setting is enabled, Internet Explorer (v. 9, 10, 11) uses the second cache mode, other browsers use the first cache mode.
     • When the Default cache mode setting is disabled, Internet Explorer (v. 9, 10, 11) uses the first cache mode, other browsers use the second cache mode.
9. The Keyboard Shortcuts option is used to customize the editors' shortcuts as users see fit:
   • Find and click on the editing symbol to the right of the shortcut you want to change.
   • Edit the existing shortcut or add an alternative key combination by clicking the New shortcut action.
   • Click OK to apply the changes.
   If you want to restore the key combinations to their default values, click the corresponding action in the top right corner.

To save the changes you made, click the Apply button.
