Article in English: When creating keyboard art, you'll typically use a plaintext editor, such as Notepad (Windows) or TextEdit (Mac), instead of a more complex editor like Microsoft Word or Pages:   Windows — Open Start, type in notepad, and click Notepad at the top of the Start window.  Mac — Open Spotlight, type in textedit, and double-click TextEdit at the top of the search results. Before you start typing random letters and symbols into your text editor, consider the subject you want to create.  Even just knowing the outline shape of the subject should be enough to get you started. Having a rough sketch of your subject may help you envision better the shapes you'll need to use. It may be tempting to attempt to create the outline for your shape and then fill it in, but creating keyboard art is much easier when you go line-by-line. For example, if you're creating a cat face, you'll want to start with the ears. Certain keys may look like obvious choices for your keyboard art, but using different keys, lowercase letters, and combinations of symbols may achieve better results. For a cat's ears, for example, your first instinct might be to use the carrot (^) key for the ears; however, using a slash (/) next to a back slash (\) will create a larger, more "ear-like" shape (/\). As your keyboard art begins to take shape, you may need to go back and change a line's spacing to fit a lower layer. For example, you may have to move an entire line forward or backward. You might also need to add an extra space between two characters to extend the line. As with any art, your keyboard image's perspective will determine whether or not the image should be symmetrical; often, one side of the image will have more spaces or characters than the other. Keyboard keys contain a wide variety of symbols and variations, but you may want to use advanced symbols (e.g., the degree symbol) for an extra layer of detail. Both Windows and Mac computers have dedicated symbol menus:   Windows — Character Map. You can open Character Map by typing character map...
