Size Adjustment Actions

Resize, grow, shrink, scale, and move windows incrementally

Overview

Size adjustment actions provide fine-grained control over window dimensions and position. Unlike positioning actions that set absolute sizes, these actions make incremental changes relative to the current window state.

Four categories of size adjustments are defined (lines 82-85):

static var sizeAdjustment: [WindowDirection] // General sizing
static var shrink: [WindowDirection]          // Directional shrinking
static var grow: [WindowDirection]            // Directional growing
static var move: [WindowDirection]            // Directional movement

General Size Adjustment

Defined in the static sizeAdjustment array (line 82):

static var sizeAdjustment: [WindowDirection] { 
    [.larger, .smaller, .scaleUp, .scaleDown] 
}

Raw Value: "Smaller"

URL Scheme: loop://Smaller

Usage Examples

Incremental Resizing

# Make window progressively larger
open "loop://Larger"
open "loop://Larger"
open "loop://Larger"

# Make window progressively smaller
open "loop://Smaller"
open "loop://Smaller"

Edge Adjustment

# Adjust only the right edge to fit content
open "loop://GrowRight"    # Expand right edge
open "loop://ShrinkRight"  # Contract right edge

# Adjust only the bottom edge
open "loop://GrowBottom"
open "loop://ShrinkBottom"

Precise Positioning

# Nudge window into perfect position
open "loop://MoveLeft"
open "loop://MoveUp"
open "loop://MoveUp"

Keyboard-Driven Workflow

Bind these to keyboard shortcuts for precise window control:

• Cmd+Ctrl+Arrow Keys: Move window
• Cmd+Option+Arrow Keys: Grow edges
• Cmd+Shift+Arrow Keys: Shrink edges
• Cmd+Plus/Minus: Larger/Smaller

Radial Menu Behavior

Size adjustment, shrink, grow, and move actions don’t have directional angles in the radial menu (line 102):

var hasRadialMenuAngle: Bool {
    let noAngleActions: [WindowDirection] = [...]
    return !(... || willAdjustSize || willShrink || willGrow || willMove)
}

They appear as menu items rather than directional triggers.

Configuration

Increment sizes for these actions are configurable in Loop’s settings:

• Size adjustment increment: Amount for .larger and .smaller
• Scale factor: Multiplier for .scaleUp and .scaleDown
• Grow/shrink increment: Amount for directional grow/shrink
• Move increment: Distance for directional moves
