Binding "enter" not working on textual app

I found two problems:

1. Enter can be already binded to application or widget and it may not react for new binding. After taking with ChatGPT I found that it may need priority=True in Binding

Binding("enter", "select", "Select", priority=True)

Doc: Binding.priority

2. Doesn't work self.focused == OptionList and it needs to use isinstance()

if isinstance(self.focused, OptionList):
    self.queryone(SelectionList).focus()

from textual.app import App, ComposeResult
from textual.binding import Binding
from textual.widgets import OptionList, SelectionList, Footer
class ToDoApp(App):
    BINDINGS = [
        Binding("q", "quit", "Quit", show=True),
        Binding("n", "new", "New ToDo", show=True),
        Binding("d", "delete", "Delete ToDo", show=True),
        Binding("j", "down", "Scroll down", show=True),
        Binding("k", "up", "Scroll up", show=True),
        # Binding("l", "select", "Select", show=True),  # to check if function is working
        Binding("enter", "select", "Select", show=True, priority=True),
    ]
    def compose(self) -> ComposeResult:
        yield OptionList("Task 1", "Task 2", "Task 3")
        yield SelectionList(("Done 1", 1), ("Done 2", 2))
        # yield Footer()
    def actionselect(self) -> None:
        # if self.focused == OptionList:
        #    self.queryone(SelectionList).focus()
        if isinstance(self.focused, OptionList):
            self.queryone(SelectionList).focus()
if name == "main":
    ToDoApp().run()

EDIT:

It seems better method is to use onoptionlistoptionselected to run code when enter is pressed on OptionList (without binding it)

This function gets event which has information about pressed option on OptionList - event.option -> Option('Task1'), event.optionindex -> 0

from textual.app import App, ComposeResult
from textual.binding import Binding
from textual.widgets import OptionList, SelectionList, TextArea
class ToDoApp(App):
    BINDINGS = [
        Binding("q", "quit", "Quit", show=True),
        Binding("n", "new", "New ToDo", show=True),
        Binding("d", "delete", "Delete ToDo", show=True),
        Binding("j", "down", "Scroll down", show=True),
        Binding("k", "up", "Scroll up", show=True),
        # doesn't need to bind to enter
    ]
    def compose(self) -> ComposeResult:
        yield OptionList("Task 1", "Task 2", "Task 3")
        yield SelectionList(("Done 1", 1), ("Done 2", 2))
        yield TextArea()
    def onoptionlistoptionselected(self, event: OptionList.OptionSelected) -> None:
        """Executed when you press Enter in OptionList"""
        textarea = self.queryone(TextArea)
        textarea.insert(
            f"--- selected ---\n{event.option=} | {event.optionindex=} | {event.optionid=}\n{event.optionlist.options=}\n"
        )
        if isinstance(self.focused, OptionList):
            self.queryone(SelectionList).focus()
if name == "main":
    ToDoApp().run()
