Autocomplete

[jonasmusall]

Proposed Enhancement

Implement an autocompletion feature for TeX input.

Requirements:

• Show list of possible command completions for current input (determined by caret position and delimiting characters).
• Respect custom macros.
• Keyboard and mouse interoperability (e.g. selecting different suggestions).
• Automatically insert and move cursor to argument brackets.
• No blocking of main window at any time.
