+# Skip Specific Pytest Test Cases
+
+While using a failing test case to build a small new feature for
+[`py-vmt`](https://github.com/jbranchaud/py-vmt), I realized I needed to do some
+refactoring first. It wasn't significant enough to warrant stashing my current
+changes and switching to a different branch, so I kept all the changes around. I
+did find the initial failing test distracting from the refactoring I was trying
+to do. To temporarily shelve that failure, I can use a Pytest decorator to mark
+it as _skipped_.
+
+```python
+@pytest.mark.skip(reason="not yet implemented")
+def test_log_recent_activity():
+    runner = CliRunner()
+
+    # set up the data dir file with some existing session entries
+    initial_datetime = datetime.datetime(
+        2026, 3, 14, 15, 5, 11, 0, datetime.timezone.utc
+    )
+    with freeze_time(initial_datetime) as frozen_datetime:
+        # ...
+```
+
+The [`@pytest.mark.skip` decorator](https://docs.pytest.org/en/stable/how-to/skipping.html#skipping-test-functions)
+tells the Pytest runner to skip of that specific test case instead of executing
+it. In the test runner output, I'll see an `s` rather than a `.` or `F` and the
+summary will include it in a count of skipped tests:
+
+```
+=========================== 3 failed, 4 passed, 1 skipped in 0.09s ===========================
+```
+
+Another way to think about this is to mark this test case as _expected to fail_
+with `@pytest.mark.xfail`. That will display as an `x` and show up in the summary as:
+
+```
+=========================== 3 failed, 4 passed, 1 xfailed in 0.11s ===========================
+```

+# List Available Zle Keybindings
+
+Unlike `bash` which uses `readline`, `zsh` has its own implementation of a line
+editing library -- `zle`. A lot of the core bindings between the two are the
+same, e.g. `Ctrl-a` and `Ctrl-e` to go the beginning and end of the command line
+prompt, respectively.
+
+All available `zle` keybindings can be listed out by running `bindkey` without
+any arguments.
+
+The best way to check out an unaltered version of this list is by starting a
+fresh `zsh` process with no RCS files loaded in. The `-f` flag does that. Note
+though that when `zsh` is starting fresh, it has to decide whether to start in
+_Emacs_ mode or _Vi_ mode. If it sees that your default editor is something like
+`vi`, `vim` or `nvim`, then it will start you in _Vi_ mode.
+
+Starting in _Vi_ mode can be confusing because none of the standard _Emacs_
+keybindings like `Ctrl-a` and `Ctrl-e` are available in that context. So first
+ensure you're in _Emacs_ mode by running:
+
+```sh
+❯ zsh -f
+lastword% bindkey -e
+```
+
+Now you can list out all the keybindings:
+
+```sh
+lastword% bindkey
+"^@" set-mark-command
+"^A" beginning-of-line
+"^B" backward-char
+"^D" delete-char-or-list
+"^E" end-of-line
+"^F" forward-char
+"^G" send-break
+"^H" backward-delete-char
+"^I" expand-or-complete
+"^J" accept-line
+"^K" kill-line
+...
+```
+
+See `man zshzle` for more details on `zle` and `bindkey`.
