Describe the feature

As title, in neovim, when using tree-sitter, we can use yank/cut/delete around class/function, or yank/cut/delete inside class/function. It's really convenient to copy/paste code.

And these keys can be:

• yac: yank around class
• dac: delete around class
• yaf: yank around function
• daf: delete around function
• yic: yank inside class
• dic: delete inside class
• yif: yank inside function
• dif: delete inside function
• cac: cut around class
• caf: cut around function
• cic: cut inside class
• cif: cut inside function

If applicable, add mockups / screenshots to help present your vision of the feature
