Blender uses a variety of different menus for accessing options and tools.Selecting menus can be interacted with in the following ways:

Mouse selection

LMB on the desired item.

Numerical selection

Avoid future problems. Before you try to fix this issue, make yourself a backup copy of all your fonts. Open Font Book, click on All Fonts, then click on any of them in the list and press Command. The Complete Guide to Blender Graphics: Computer Modeling & Animation, Fifth Edition.

MacOS uses “files” with the.app extension called applications.These files are actually folders that appear as files in Finder. In order to run Blender you will have to specify that path to the Blender executable inside this folder, to get all output printed to the terminal.
Overall, the Logitech M570 is for many the best wireless mouse for Mac, due to its ergonometric design, which supports the user during long and intensive hours of work. Remote desktop apps for iPad let you take control of your computer, or someone else's if given permission, in order to view and transfer files while on the go.

You can use the number keys or numpad to input an item in the list to select.For example, Numpad1 will select the first item and so on.

If the menu content is too large to fit on the screen, small menuscrolling indicator triangle appears on bottom or top of menu.Scrolling is done by moving the mouse below or above the scrolling indicator.

Shortcuts

Use Wheel while hovering with the mouse.
Arrow keys can be used to navigate.
Each menu item has an underlined character which can be pressed to activate it.
Number keys or numpad can be used to access menu items.(Where 1 is the first menu item, 2 the second, etc.For larger menus Alt-1 the 11th… up to Alt-0 the 20th.)
Press Return to activate the selected menu item.
Press Esc to cancel the menu, or move the mouse cursor far from the pop-up,or by LMB clicking anywhere out of it.

Header Menus¶

Most headers exhibit a set of menus, located at the start of the header.Header menus are used to configure the editor and access tools.All menu entries show the relevant shortcut keys, if any.

Collapsing Menus¶

Sometimes it’s helpful to gain some extra horizontal space in the header by collapsing menus.This can be accessed from the header context menu,click RMB on the header and select Collapse Menus.

Access the menu from the collapsed icon.¶

Select Menus¶

The Select menu (short selector) lets you choose between a set of options.Select menu appears as an icon and/or text with down arrow on the right side of the button.The menu options are shown with LMB click on the button.The selected option is then shown as active on the menu button.You can also use Ctrl-Wheel to cycle through options without opening the menu.

Popover Menus¶

Popover menus are overlays.Like Select Menus, pop-up menus also include down arrow on the rightside of menu button. However, pop-up menus allow more content to be shown,such as title, list options, buttons, sliders, etc.Popover menus group controls into a menu, which is automatically hiddenwhen mouse pointer leaves menu boundaries (including a margin).

Context Menu¶

Context menus are pop-ups opened with the Menu key for editors and RMB for properties.Context menu contents depend on the location of the mouse pointer.

When invoked in an editor the menu contains a list of operators sensitive to the editor’s mode.Or when invoked over buttons and properties common options include:

Single

Set or get single value.

All

Include all combinations.

Reset to Default Value(s) Backspace

Replaces the current value by the default.

Copy Data Path Shift-Ctrl-C

Copies the Python property Data path, relative to the data-block.Useful for Python scripting.

Copy Full Data Path Shift-Ctrl-Alt-C

Copies the full Python property Data path including any needed context information.

Copy As New Driver

Creates a new driver using this property as input, and copies it to the clipboard.Use Paste Driver to add the driver to a different property, or Paste Driver Variablesto extend an existing driver with a new input variable.

Copy To Selected

Copies the property value to the selected object’s corresponding property.A use case is if the Properties context is pinned.

Assign Shortcut

Fastest way to operate a Pie menu is to press down key(s) thatinvoke the menu, then move mouse slightly towards a selection, andrelease key(s) to activate the selection.

Releasing the key without moving the mouse will keep the menu open andthe user can then move the mouse pointer towards the direction of a pie menu item and select it by clicking.Releasing the key, after moving the mouse towards a pie menu item, will cause the menu to close andthe selected menu item to activate.

An open disc widget at the center of the pie menu showsthe current direction of the pie menu. The selected item is also highlighted.A pie menu will only have a valid direction for item selection,if the mouse is touching or extending beyond the disc widget at the center of the menu.
