This is because `ttotp` tries to only clear values that it set,
by checking that the current clipboard value is equal to the value it pasted earlier.
Search for a key by pressing "/" and then entering a modified case insensitive regular expression.
Search for a key by pressing "/" and then entering sub-strings to search for.
Press Ctrl+A to show all keys again.
In this type of regular expression, a space ` ` stands for "zero or more characters, followed by whitespace, followed by zero or more characters"; the sequence backslash-space stands for a literal space.
Textual's built in [fuzzy match](https://textual.textualize.io/api/fuzzy_matcher/) algorithm is used.
This makes it easy to search for e.g., "Jay Doe / example.com" by entering "ja d ex", while not requiring any sophisticated fuzzy search technology.
