Additional keybinds and utility functions

The following adds a shortcut to move lines (and blocks of lines in visual mode) up and down using alt-j/k:

--Add move line shortcuts
vim.api.nvim_set_keymap('n', '<A-j>', ':m .+1<CR>==', { noremap = true})
vim.api.nvim_set_keymap('n', '<A-k>', ':m .-2<CR>==', { noremap = true})
vim.api.nvim_set_keymap('i', '<A-j>', '<Esc>:m .+1<CR>==gi', { noremap = true})
vim.api.nvim_set_keymap('i', '<A-k>', '<Esc>:m .-2<CR>==gi', { noremap = true})
vim.api.nvim_set_keymap('v', '<A-j>', ':m \'>+1<CR>gv=gv', { noremap = true})
vim.api.nvim_set_keymap('v', '<A-k>', ':m \'<-2<CR>gv=gv', { noremap = true})

The following adds a toggle to disable indentlines for easier mouse block pasting:

-- Toggle to disable mouse mode and indentlines for easier paste
ToggleMouse = function()
  if vim.o.mouse == 'a' then
    vim.cmd[[IndentBlanklineDisable]]
    vim.wo.signcolumn='no'
    vim.o.mouse = 'v'
    vim.wo.number = false
    print("Mouse disabled")
  else
    vim.cmd[[IndentBlanklineEnable]]
    vim.wo.signcolumn='yes'
    vim.o.mouse = 'a'
    vim.wo.number = true
    print("Mouse enabled")
  end
end

vim.api.nvim_set_keymap('n', '<F10>', '<cmd>lua ToggleMouse()<cr>', { noremap = true })
