If you cannot find a specific command, you might like to give a look at the gui.xml file which contains the definitions of menus / commands + the parameters.

To figure out the parameters of an undocumented command, you can:

Choose a command (the CommandName part of app.command.CommandName) from gui.xml file ( <key command="CommandName" ...> or <item command="CommandName" ...>)
If those <key>...</key> or <item>...</item> XML elements contain children elements like <param name="param-name1" value="param-value2" /> you can specify those parameters in Lua between { ... }, for example:
lua
```
app.command.CommandName { ["param-name1"]="param-value1", ["param-name2"]="param-value2" }
```

Another alternative is looking to the Aseprite source code:

Choose the command you want to use and find its counterpart .cpp file in src/app/commands/ (e.g. app.command.CropSprite has the file cmd_crop.cpp)
Find all places in the file where params.get is used, the strings in that function are the parameter names you need to use.
When setting the parameters, you'll want to write the parameters as below because Lua does not accept hyphens in identifiers.
lua
```
app.command.CommandName { ["parameter-name"]="value", ["other-parameter-name"]="otherValue" }
```
