Showing custom UI panel in Blender by pressing keycodes

When creating add-ons for Blender, developers almost always create the user UI panel with tools that provide the main functionality of the add-on. Typically, such custom panels are placed in the N-panel block, called by pressing the N key. However, if it is assumed that the user will often call the panel with add-on tools, its call can be bound to a keyboard shortcut and the panel can be called from the keyboard.

Setting an icon from the tools panel to a button in the custom UI panel in Blender

To set an icon to a button when creating the custom user UI panel in Blender, we look for the text identifier of the desired icon (usually using the built-in Icon Viewer add-on) and set its value to the “icon” parameter when binding the desired operator to the button. However, the icons used in the tools panel are not existed in the common Blender icons list.
