Notes about the command format:

• Words in UPPER_CASE are the parameters to be supplied by the user.
  e.g. in todo NAME, NAME is a parameter which can be used as todo Defeat Gengar.

Adding a task: todo / event / deadline

Format:

• Adding a todo: todo NAME
• Adding an event: event NAME /at DATE

Format: list

Locating tasks by name: find

Find tasks where names and / or dates contain any of the given keywords.

Format: find KEYWORD

• The search is case-sensitive. e.g Save will not match save
• A space-separated search is considered as one keyword e.g. Save Mudkip would match Save Mudkip only, and not Save Treecko
• Both the name and date can be searched.
• Partial words can be matched e.g. Mud will match Mudkip

Examples:

• find Sav returns Save Mudkip /by 2020-09-09 and Save Treecko
