# [Blogs](../blog/) >> Mnemonic key bindings navigation
2018-01-30 20:33:04 +08:00
You don't need to remember any key bindings, as a guide buffer is displayed each time the prefix key is pressed
in normal/visual mode. It lists the available key bindings and their short description.

The prefix can be `[SPC]` , `[Window]` , `<leader>` , when the guide is opened, you can
see the prefix on the statusline.
This will be shown in floating windows if your vim/neovim support this feature.
- vim: `8.1.1364`
- neovim: `v0.4.2`

Otherwise, it will be displayed in split Window.

## default key binding prefixes
2020-08-01 10:51:28 +08:00
| Prefix name | custom option and default value | description |
| ----------- | ------------------------------------------------------- | ---------------------------------- |
| `[SPC]` | NONE / `<Space>` | default mapping prefix of SpaceVim |
| `[Window]` | `g:spacevim_windows_leader` / `s` | window mapping prefix of SpaceVim |
| `<leader>` | `mapleader` / `\` | default leader prefix of vim/neovim |

By default the guide buffer will be displayed 1000ms after the key has been pressed. You can change the delay by setting `'timeoutlen'` option to your liking (the value is in milliseconds).
for example, after pressing `<Space>` in normal mode, you will see :

this guide show you all the available key bindings begin with `[SPC]` , you can type `b` for all the buffer mappings, `p` for project mappings, etc.
