add symbol shortcuts like Confluence

In Confluence, I've gotten used to being able to write some frequently used symbols with a shortcut. For example, I create a green check mark by typing (/).

It would be great if this feature were also implemented in Docmost. Currently, you can only select symbols with the mouse after typing :. However, the selection of symbols does not match the symbols I use frequently.

These are:
• Green check mark (/)
• Red X (x)
• Question mark (?)
• Exclamation mark (!)
• Star (*)
• Thumbs up (y)
• Thumbs down (n)
• Plus (+)
• Minus (-)
• Light bulb (on)
