+# toggleterm-manager.nvim
+
+A Telescope extension to manage Toggleterm's terminals in NeoVim
+
+Key `<Leader>ts` is mapped to open the telescope interface.
+
+Additionally added keymaps in the Telescope interface:
+
+- `n` normal mode:
+  - `<CR>`: toggle the selected terminal.
+  - `r`: rename the selected terminal.
+  - `d`: delete the selected terminal.
+  - `n`: create a new terminal buffer
+- `i` insert mode:
+  - `<CR>`: toggle the selected terminal.
+  - `<C-r>`: rename the selected terminal.
+  - `<C-d>`: delete the selected terminal.
+  - `<C-i>`: create a new terminal buffer
