+-- ===
+
+-- leader键设置为空格,; as :
+vim.g.mapleader = " "
+mapkey("", ";", ":")
+
+-- 上/下一个搜索结果以及取消搜索结果高亮
+mapkey("", "=", "nzz")
+mapkey("", "-", "Nzz")
+mapcmd("<leader><cr>", "nohlsearch")
+
+-- 保存和退出
+mapkey("", "S", ":wall<cr>")
+mapkey("", "Q", ":q<cr>")

+-- 撤销与反撤销
+mapkey("", "l", "u")
+mapkey("", "L", "<c-r>")
+
+-- 插入
+mapkey("", "k", "i")
+mapkey("", "K", "I")
+
+-- 以下两个映射默认了
+-- make Y to copy till the end of the line
+-- mapkey('','Y','y$')
+
+-- make D to delete till the end of the line
+-- mapkey('','D','d$')
+
+-- 折叠
+mapkey("", "<leader>o", "za")
+mapkey("x", "<leader>o", "zf")
+-- 读取保存的折叠
+-- mapkey("", "<leader>a", ":loadview<cr>")
+
+-- 打开lazygit,已用fm-nvim插件
+-- mapcmd('<c-g>',':tabe<CR>:-tabmove<CR>:term lazygit')
+
+-- ===
+-- === Cursor Movement
+-- ===
+-- New cursor movement (the default arrow keys are used for resizing windows)
+
+--     ^
+--     u
+-- < n   i >
+--     e
+--     v
+
+mapkey("", "n", "h")

+
+-- faster navigation
+mapkey("", "U", "5k")
+mapkey("", "E", "5j")
+mapkey("", "N", "0")
+mapkey("", "I", "$")
+
+-- 更快的行导航
+mapkey("", "W", "5W")
+mapkey("", "B", "5B")
+
+-- ===
+-- === Window management
+-- ===
+
+-- Disable the default s key
+mapkey("", "s", "<nop>")
+
+-- 使用<space> + 新方向键 在分屏之间移动
+mapkey("", "<LEADER>w", "<C-w>w")
+mapkey("", "<LEADER>u", "<C-w>k")
+mapkey("", "<LEADER>e", "<C-w>j")
+mapkey("", "<LEADER>n", "<C-w>h")
+mapkey("", "<LEADER>i", "<C-w>l")
+
+-- 使用s + 新方向键 进行分屏
+mapcmd("su", "set nosplitbelow<CR>:split<CR>:set splitbelow")
+mapcmd("se", "set splitbelow<CR>:split")
+mapcmd("sn", "set nosplitright<CR>:vsplit<CR>:set splitright")
+mapcmd("si", "set splitright<CR>:vsplit")
+
+-- 使用方向键来调整窗口大小
+mapcmd("<up>", "res +5")
+mapcmd("<down>", "res -5")
+mapcmd("<left>", "vertical resize-5")
+mapcmd("<right>", "vertical resize+5")
+
+-- 使分屏窗口上下分布
+mapkey("", "sh", "<C-w>t<C-w>K")
+-- 使分屏窗口左右分布
+mapkey("", "sv", "<C-w>t<C-w>H")
+
+-- 按 <SPACE> + q 关闭当前窗口下方的窗口
+mapkey("", "<LEADER>q", "<C-w>j:q<CR>")
+
+-- ===
+-- === Tab management
+-- ===
+
+-- tu创建新标签
+mapcmd("tu", "tabe")
+-- 在标签之间移动,已用bufferline.nvim替代
+-- mapcmd('tn','-tabnext')
+-- mapcmd('ti','+tabnext')
+
+-- 移动标签的位置
+-- mapcmd('tmn','-tabmove')
+-- mapcmd('tmi','+tabmove')
+
+-- 关闭当前标签,已用close-buffers替代
+-- mapcmd('tq','tabc')
+
+-- ===
+-- === 批量缩进方法
+-- ===
+-- 操作为，esc从编辑模式退到命令模式，将光标移到需要缩进的行的行首，然后按shift+v，可以看到该行已被选中，且左下角提示为“可视”
+-- 按键盘上的上下方向键，如这里按向下的箭头，选中所有需要批量缩进的行
+-- 按shift+>,是向前缩进一个tab值，按shift+<，则是缩回一个tab值
+
+mapkey("x", "<", "<gv")
+mapkey("x", ">", ">gv")
+mapkey("x", "<s-tab>", "<gv")
+mapkey("x", "<tab>", ">gv")
+
+-- ===
+-- === Other useful stuff
+-- ===
+
+-- 打开一个终端窗口
+mapcmd("<LEADER>/", "set splitbelow<CR>:split<CR>:res +10<CR>:term")
+
+-- 按两下空格跳转到占位符<++>,并进入插入模式
+mapkey("", "<LEADER><LEADER>", "<Esc>/<++><CR>:nohlsearch<CR>c4l")
+
+-- 拼写检查
+mapcmd("<LEADER>sc", "set spell!")
+
+-- 运行代码
+
+vim.cmd([[
+ au filetype dart noremap r :wall<cr>:term tmux a <cr>
