Basic Alt Key/Entry Script - Simplest Script Ever

Hi - for a coder this may well be the easiest question you ever come across! All I want to do is write a script to select draw 'Trendline' in MT4, so it's ready to click and draw. This can be achieved with: (Alt+I) L T

Can anyone quickly advise how can I put the above into a script so I can assign a hotkey to it to make it quicker to use?

Cheers

Turns out despite what it looks like it's not so simple to program after all! Looks like an external hotkey program is the best way perform functions like this.
