-- Exec word should try to match lua function calls (first match word, then expand selection right)
 - Remove pointers and use ViewIDs (enable array debug while doing this)
 - try using git grep for search for now, combine with fuzzy search buffer
 - need to rewrite the path matching in lua
-- I think clipboard adds \r\n, let's execute the conversion on that
 - prevent lua from infinite looping
 - Append to console and change console directory
-- hotkey to select window title
-- the 'invisible when inactive' flag does it apply to title bar windows??
+- win32: change all stack buffers to arena
 
 - search as a command to execute which is going to be in the title bar
 - search backwards
 - braces enclose should be performed even if we put the mouse out of bounds!
 - select until
 - some split selection commands
+- assign commands or lua functions to F1-F12 keys
 
 - word complete
 - Search all buffers in 10X style, incrementally searched results popping up on every key press (maybe we need coroutine library in C so this is easier?)
