指令
为了加快您的工作效率，您可以将这些指令绑定至CFG脚本内。例如, Left 4 Dead (L4D)的nav_mode.cfg。 注意：区域可以等于导航网络。 词条翻译：求生的兔（OKcf）。欢迎补充修正。
导航网络（网格）生成
- nav_mark_walkable
- 标记一个位置，以这个以这个位置进行生成导航网络（这个仅标记，需要配合nav_generate或nav_generate_incremental生成，一般用后者）。
- nav_clear_walkable_marks
- 消除地图内所有标记点。
- nav_generate
- 为当前地图生成导航网络并保存至磁盘。
- nav_generate_incremental
- 在不改变现有存在nav的情况之下，增加新的导航网络。比如生成的导航网络有些地方没有被覆盖，可以利用这个填充那个部分并且不会修改原有已生成的导航网络。
Note that these new areas will have to be manually connected to the existing mesh.
- nav_generate_incremental_range <integer>
- 设置导航网络一次生成的距离（单位？），以标记点位中心。
- nav_auto_build_area
- Build out high-precision areas around the edit cursor and create them.
- nav_save
- 保存当前地图的导航网络至磁盘。
- nav_analyze
- 分析当前已生成的导航网络并将其保存至磁盘。分析会更加精确地定义BOT（求生之路则是电脑玩家和感染者）的二阶数据，以更换规划他们的行为系统。
- nav_load
- 为当前地图导入导航网络。
Selection commands
- nav_add_to_selected_set
- 将当前区域添加至所选集合内，通常是光标所指位置。
- nav_add_to_selected_set_by_id
- 将明确的导航网络ID进行选择，一般对于后期处理错误很有帮助。
- nav_begin_deselecting
- Start continuously removing from the selected set.
- nav_end_deselecting
- Stop continuously removing from the selected set.
- nav_begin_selecting
- 选择一个批量选择开始点。
- nav_end_selecting
- 选择一个批量选择结束点。
- nav_begin_drag_deselecting
- Start dragging a selection area.
- nav_end_drag_deselecting
- Stop dragging a selection area.
- nav_begin_drag_selecting
- Start dragging a selection area.
- nav_end_drag_selecting
- Stop dragging a selection area.
- nav_toggle_in_selected_set
- 选择光标对准的导航网络，通常可以绑定一个按键。例如，nav_mode.cfg 在求生之路1的配置文件内，绑定按键为“z”。
- nav_clear_selected_set
- 取消所有选择的导航网络。
- nav_flood_select
- Selects/highlights all nav meshes that are connected, starting with the nav mesh that the in-game gun crosshair is pointing at. This does not mean that all nav mesh areas are selected.
- select_with_attribute
- Selects/highlights all nav mesh areas marked with one attribute specified.
Editing commands
- nav_delete
- 删除选择的导航网络。
- nav_delete_marked
- 删除当前标记的区域（如果有。）
- nav_split
- 拆分导航网络，方法是对准某个导航网络，导航网络将会出现一条线，以此条线来拆分导航网络。
- nav_make_sniper_spots
- Chops the marked area into disconnected sub-areas suitable for sniper spots.
- nav_chop_selected
- Chops all selected areas into their component 1x1 areas

- nav_mark
- 标记区域或者梯子，以便后续操作。
- nav_unmark
- 取消标记区域或者梯子。
- nav_begin_area
- 手动创建一个导航网络的一个对角，然后以相对方向拖动鼠标以规划区域，输入“nav_end_area”完成创建。
- nav_end_area
- 完成手动创建的导航网络。
- nav_connect
- 连接两个导航网络。选中一个导航网络对准另一个导航网络，并输入此指令。请注意：这样做是单向连接，比如以求生之路为例，上单向连接下，则感染者可以从上下来，但是他们不会从下上去。所以如果你需要双向连接请选择两个导航网络。
- nav_disconnect
- 取消导航网络的连接。
- nav_splice
- 选择两个导航网络，然后输入此指令，由系统自动创建两个导航网络的空缺部分。
- nav_corner_select
- Select a corner of the currently marked Area. Use multiple times to access all four corners.
- nav_corner_raise

- nav_begin_shift_xy
- Begin shifting the Selected Set.
- nav_stop_shift_xy
- Finish shifting the Selected Set.
- nav_simplify_selected
NAV修正命令
修改某个导航网络的属性，这样被修改的区域可以强制bot进行一些操作，比如在此区域强制下蹲，遵循某路线前进或者是禁止在此区域生成等。像是“mark CROUCH”与命令“nav_crouch”效果一致。例如，在求生之路中，有 属性列表来为求生之路的僵尸生成和电脑人控制进行应用。
