Hardcoded shorcuts or options which cannot have shorcuts

Problem

There are some hard-coded shortcuts which should be editable

This means:

• shortcuts that override hard-coded ones won't work when canvas is active (and hard-coded shortcut is activated instead) see inkscape#838
• hard-coded shortcuts that aren't in the Shortcuts file list are hard to discover and can't be changed

Rest of the description are examples of hardcoded shortcuts:

Action	Key
Quick Zoom	Q
Hide Overlays	F
Node Editor: Join Nodes etc.	None
Align and Distribute	Numpad Keys
Bezier Tool: Make last segment line Make lastsegment curve	While Drawing Ctrl+L Ctrl+U
Reflect Gradient	Shift+R
Hide Selected Objects	None
Lock Selected Objects	None
Unset Storke/Fill	None

node tool - toolbar

basically all tools here are hard-coded and don't even have shortcuts in tip tools

align and distribute dialog

all distribute tools are not shorcut-able and are missing shortcuts in tip tools

Bezier tool

Shift+L make last segment line Shift+U make last segment curve

Gradeint tool

shift+R reflect gradeint

Context menu

• hide selected objects
• lock selected object

context menu on colors in info bar

• Unset stroke
• Unset fill

more

I know there is more of them but for now, this is what I found
