Sizer for Windows

When a browser window needs to match a particular screen size for a layout check, dragging its edges can be imprecise. Sizer lets you choose saved window dimensions and positions, then apply them from a resizing menu or with a hotkey.

How do you apply a saved size?

Sizer adds a menu of resize actions for the active window. In the documented border workflow, move the pointer to a window edge or corner until a resize cursor appears, then right-click to open the menu and select an entry. A hotkey can bring up the resizing menu without locating the border; the default shortcut shown in the guide is Ctrl+Win+Z.

Custom dimensions and placement

Define entries with a name, width, and height, then choose where the window should be placed. Sizer can position a window as well as resize it, so a saved action can put its top-left corner at a chosen location. Menu groups organize entries into cascading submenus when the list needs structure.

• Use macros and expressions to calculate dimensions or positions, including values based on the current monitor.
• Macros can arrange several windows together, while wildcard matching can apply actions to matching windows.
